On a 2023 episode of her "B**** Sesh" podcast, as reported by Variety, actress Casey Wilson shared a story about working with Tim Allen on an episode of his Disney+ series "The Santa Clauses," which is a sequel show to Tim's "The Santa Clause" movie franchise. She called it "the truly single worst experience I've ever had with a co-star ever," branding Tim "such a b****."
According to the "Saturday Night Live" and "Happy Endings" alum — who was initially reluctant to share the tale because one of the producers was a great friend and because her children loved the "Santa Clause" films — when she guest starred on the series' 2022 pilot episode, Tim was beyond rude. Casey claimed "everybody was walking on eggshells" around him. "People just looked frantic."
She recounted being in a scene with the Emmy-nominated "Home Improvement" actor where "I'm supposed to throw things at him. I think he's a burglar. So he's coming down the chimney, obviously as Santa, and I am woken up thinking there's an intruder, basically like a home invasion scene," she recalled. "[He] goes over to the producer who is standing four feet from me and goes, and I hear him, he goes, 'You gotta tell her to stop stepping on my lines.' The producer turns to me with horror on his face and has to walk one foot to me and he goes, 'Um, Tim would ask that you stop stepping on his lines.'"
When Tim was done shooting, "He was so f****** rude," Casey said. "Never made eye contact, never said anything. It was so uncomfortable." She also recalled his grand exit when he was done. "It's the end, and Tim Allen goes, 'Leaving!' [and] takes his Santa cape, picks it up and drops it on the floor and walks out," she recalled. "And they hustle in his stand-in; lovely man, who was much nicer to act against. People are scurrying to pick up his velvet Santa coat. He's a b****. And this is the best… I will not say who said this. This was someone that I do not know, perhaps in the crew. [He or she] breezes past me and just goes, 'You're seeing him on a good day.'"

During an appearance on E! News in September 2023, Sharon Osbourne played a game called "Stir The Pot."
After being asked to "name the worst celebrity" she's ever met, she didn't hesitate.
"The guy that's married to that actress, and he used to do 'That '70s Show,"' she said. After confirming that she was referring to Ashton Kutcher, Sharon continued, "Oh, yes. Oh, rude, rude, rude, rude little boy." The former "The Talk" host didn't get specific about her run-in with Ashton, but added that he's a "dastardly little thing."

Valerie Bertinelli had a Dirrty encounter with this pop star…
_
In 2014, Valerie Bertinelli told "Watch What Happens Live" host Andy Cohen about an icy exchange she had with Christina Aguilera. The actress said she saw the pop star at one of ex-husband Eddie Van Halen's concerts. "I was a fan at that time and I went up to her because she was at a Van Halen concert, and I said, 'Oh my God, I think you're a beautiful singer,'" Valerie said. "And she just went like, 'Yeah, whatever.' She gave me the cold shoulder, and I thought, 'B****, I'm a fan. You can't be nice to me?'" When Andy asked if she's seen Christina since that day, Valerie shaded, "I have not, no. But you know what? She might have gotten better, but I heard she hasn't."

In 2023, "The Real Housewives of New Jersey" star Teresa Giudice shared details of her encounter with an actress she felt was incredibly rude…
_
Teresa Giudice's one-sided feud with Sofia Vergara goes back years. The "Real Housewives of New Jersey" star called the "Modern Family" actress the "rudest" celebrity she's ever met during an episode of her "Namaste B******" podcast. Some of Teresa's ire seems to stem from Sofia not knowing who the reality TV star was. Back in 2017, Sofia was reluctant to snap a pic with Teresa at a talk show. "Sofia Vergara's PR person and my PR person spoke together, and I guess the two of them said, 'Let's get a picture of Teresa and Sofia together,'" Teresa recalled in 2023.
"I didn't want a picture with her. I've never asked to take a picture with anybody. [She's] the rudest woman I've ever met." In describing the interaction, Teresa seemed to mock Sofia's Colombian accent and said she should be "nice" because she's an "immigrant." "I saw her whole demeanor, and then I heard her say to her PR person, 'Why are you making me take a picture with that lady?' I was like, 'Excuse me? I did not want to take a picture with you! I never asked to take a picture with you,'" Teresa claimed. "I was like, 'How rude. You're so not a humble person. You forgot where you came from.'"

_
Deena Cortese told Andy Cohen on "Watch What Happens Live" in 2023 that Ryan Reynolds, a man pretty much universally loved, was "not great" to her. "I truly love Ryan Reynolds still, and I love [his wife] Blake Lively, so when he didn't wanna be by us, I was like, 'Oh my God!'" she said. Co-star Sammi "Sweetheart" Giancola was also present during that unfortunate encounter and chalked it up to Ryan having "a bad day."

In July 2022, JoJo Siwa was asked who the rudest celebrity she ever met was. Her answer was not expected…
_
JoJo Siwa surprised fans when she publicly identified Candace Cameron Bure as the "rudest" celebrity she's come across. The situation stemmed from a red carpet moment in which Candace denied a then-11-year-old JoJo a picture. In an Instagram video, Candace said she felt "crummy" hearing the story and apologized numerous times for "breaking" the child star's heart. JoJo and Candace apparently hashed it out, but the "Full House" star felt there was a lesson to be learned. "Even a 10-second trending TikTok video can do damage because our words matter and our actions matter," she said. "Be mindful of what we do post, even if it's meant to be innocent and fun at the time." JoJo later opened up about it, saying in a video posted by Page Six, "I was 11 and I was a big, big fan, and I wanted to take a picture with her, and it wasn't a good time for her." However, JoJo added, just "because I had a bad experience, that doesn't mean that she is an awful human."

This Spice Girl had no qualms ripping a former late night show host…

Mel B dubbed James Corden the "biggest d*******" in Hollywood. The Spice Girl appeared on Britain's "The Big Narstie Show" in 2022 and was asked to name the worst celebrities she's ever met. Mel rattled off a few names who she found "annoying," but her unhappiness was really aimed at the former late night host. "I think you always have to be nice to the people that you work with — whether it be production, camera guys, sound, lighting," she said. "We all work for the same thing, so you should always be nice, and he hasn't been very nice."

During a "Spill Your Guts or Fill Your Guts" segment on "The Late Late Show" in 2017, James Corden identified Pierce Brosnan as the rudest celeb he's ever met. "I don't think he's a rude man, he just happened to be [to me]," the comedian and host said. Detailing the situation, James recalled, "I went to see U2 … and Pierce Brosnan was with some friends here, and they left halfway through the gig to go off. … So me and my wife moved into this area. And literally … this arm went on here and just pushed me out the way. And I looked at him like that, and he didn't even glance at me." James summed up the experience by saying, "Maybe he's just a bit f****** rude."

_
Tia Mowry recalled the time she saw Charlize Theron at a SoulCycle class. "She wasn't very nice to me," Tia told In Touch in 2014. "I said, 'Hi,' and she actually rolled her eyes and said, 'Oh my God.' I wasn't over-the-top. I know how to approach another celebrity." Charlize was later asked about the moment on "Watch What happens Live" and didn't recall it. She was also skeptical about whether it happened, wondering if Tia's comments were taken out of context. "I'm really nice at SoulCycle, actually, because once my endorphins kick in … I'm actually almost too friendly," Charlize said, adding, "I'm not an eye roller."

"Hammy showed up. … He even said to me, 'What are you doing here?' I said … 'What are you doing here?'" Then she said an intoxicated Jon interrupted her while she was chatting with Jack Nicholson. She alleged that the "Mad Men" star whispered in her ear, "You know your Emmy isn't a real Emmy." She also claimed his whispering continued with, "You're so o-o-o-old."

Jon Stewart had something to say to this notoriously crabby guest…

In 2009, Hugh Grant appeared on "The Daily Show" to promote his film "Did You Hear About the Morgans?" The actor was not enthralled with the movie clip that was shown. "What is that clip? It's a terrible clip," Hugh said angrily. Jon shot back, "Well, then make a better f****** movie." A few years later, Jon told pal and fellow host Stephen Colbert that the rom-com actor was "a big pain in the a**." With time to recalibrate his thoughts, Hugh admitted he was in the wrong. "Turns out my inner crab got the better of me with TV producer in 09. Unforgivable. J Stewart correct to give me kicking," he wrote on social media.

During the Black Lives Matter protests in 2020, Lea Michele took to social media to support the movement. Samantha Marie Ware, who appeared alongside Lea on 11 episodes of "Glee," wasn't having it. "LMAO REMEMBER WHEN YOU MADE MY FIRST TELEVISON GIG A LIVING HELL?!?! CAUSE ILL NEVER FORGET," Samantha wrote in all caps. "I BELIEVE YOU TOLD EVERYONE THAT IF TOU HAD THE OPPORTUNITY YOU WOULD 'S*** IN MY WIG!' AMONGST OTHER TRAUMATIC MICROAGRESSIONS THAT MADE ME QUESTION A CAREER IN HOLLYWOOD…"
After Samantha spoke out, others came forward to claim Lea was incredibly rude to them too. Actress Monica Moskatow penned an Instagram message recounting an exchange with Lea. "September 2009 I was hired to work at the premiere party for Glee at a high school. They hired lookalikes of the shows characters to perform at the party. I was the Rachel Berry lookalike," Monica wrote, referring to Lea's character on the FOX show. "I didn't know my character was the lead let alone who played her. When the actors arrived at the event and found out there were lookalikes of them Lea came searching for me. When she saw me she said, 'Oh my god! Could they have picked someone uglier!'" "The Real Housewives of New York City" alum Aviva Drescher also claimed Lea was once "very unkind" to her.

Jim Carrey said he "still loves" this actor despite an unpleasant encounter.
_
While appearing on "Norm Macdonald Live" in 2017, Jim Carrey recalled his excitement when seeing Tommy Lee Jones at a restaurant. Tommy was, shall we say, less excited. "I went over and I said, 'Hey Tommy, how are you doing?' and the blood just drained from his face. And he got up shaking — he must have been in mid kill me fantasy or something like that," Jim said. "And he went to hug me and he said, 'I hate you. I really don't like you.' And I said, 'What's the problem?' and pulled up a chair, which probably wasn't smart. And he said, 'I cannot sanction your buffoonery.'"
