Nothing makes us cringe quite like a celebrity couple who fumbles their face-sucking. From uncomfortable cuddling to klutzy puckering, here are some of the most awkward celebrity PDA moments ever, starting with Robert Pattinson and Kristen Stewart, who purposely, yet all too convincingly, flubbed a lip-lock at the 2010 MTV Movie Awards.
Nearly a year after Jennifer Lopez and Marc Anthony parted ways after seven years of marriage, they reunited onstage in Las Vegas for a live version of their "¡Q'Viva! The Chosen" variety show. The crooner went in for a hug and ended up nibbling some refreshing life blood out of his estranged wife's chin. Keep clicking for still more uncomfortable J.Lo PDA …
Who would have guessed that this relationship was doomed to fail? Oh, yeah: everyone. A spiffed-up and spray-tanned Ben Affleck eyes an escape route as then-fiancée Jennifer Lopez gives him a smooch at the 2003 Oscars. A few months later, the media beast known as Bennifer called off their elaborate nuptials before finally parting ways for good in January 2004. J.Lo reportedly returned her 6.1-carat pink-diamond engagement ring to Affleck.
Katherine Heigl isn't a big fan of facial hair, even when it's on her husband, Josh Kelley.
Rumor has it that Jennifer Aniston's inconstant romance with John Mayer was already on life support when they stepped out at the 2009 Academy Awards, where she presented in front of a crowd that included Brad Pitt and Angelina Jolie. Not surprisingly, soon after Jen squirmed and made this please-stop-touching-me face in John's embrace at a post-Oscars bash, they once again pulled the plug on their relationship.
In 2006, Ryan Phillippe celebrated wife Reese Witherspoon's Golden Globe win for "Walk the Line" by greedily gnawing on her cheek. Nine months and one Oscar win later, their marriage was kaput amid rumors that he strayed.
Sadly, this is the least squicky moment from Liza Minnelli's, ahem, romance with David Gest.
What makes Kelsey Grammer so darn irresistible to the opposite sex? Is it his masculine forehead? His seasoned osculatory skills? His flowery taste in board shorts? The actor leans in to give wife No. 4, Kayte Walsh, a taste of his tossed salad and scrambled eggs during a tropical vacation.
As Donald Trump receives a buss from wife Melania Trump at the 2012 Costume Institute Gala, he unwittingly imitates the face of everyone who's ever seen his hair and skin tone up close.
The cold, dead eyes of Doug Reinhardt contrast sharply with the cuddle-bunnies offered by Paris Hilton. It's almost as if he realizes the only reasonable response to being forced into a be-winged tutu is a total mental shutdown. Or maybe he knows things could get worse …
We can almost hear Paris whispering passionate sweet nothings to Doug Reinhardt, like, "Do you think this sore on my tongue is something I should worry about?"
Hugh Hefner has had many, many (many) decades to perfect his make-out technique on the willing lips of a parade of Playboy-posing blondes. Here, Holly Madison breathes in the scent of Benefiber and Viagra as she awkwardly puckers up with Hef.
Kim Kardashian's spotlight addiction says yes, but her sealed mouth says no as her hubby of 72 days, Kris Humphries, leans down for a kiss.
Do you think Jared Leto looks back at his romance with a clearly smitten Scarlett Johansson and thinks, "Maybe I should have paid more attention to her scorching hotness instead of staring at my phone?"
Tom Cruise and Katie Holmes have thankfully toned down the PDA cringe-apalooza that characterized their early days, when he'd try to suck her soul out through her mouth and she'd cling to him like a baby remora. But the memories of TomKat's graceless canoodling linger on, like in this shot: Note how Cruise smashes his trademark grin into Holmes' face as he keeps an iron grip on her back and one hand at the ready in case she tries to make a break for it.
It's nice to see that perfect pair Gisele Bundchen and Tom Brady aren't good at everything. The genetically favored flames go offside in their game of tonsil hockey as she gazes into the distance and he does an impression of a chimpanzee with a banana craving.
Wiz Khalifa and Amber Rose say hello the French way at the 2011 BET Awards.
If Simon Cowell were judging this kiss with his onetime fiancée, Mezhgan Hussainy, he'd probably sneer, "Amateurish. I mean, really just terrible. Your pucker is off, the technique is sloppy and there's absolutely no emotion. You may as well be sucking up to a Hoover. Quite possibly, you're the worst kisser in the world. Just dreadful."
The well-known wandering eye of Monaco's Prince Albert didn't stop roaming when he tied the knot with Charlene Wittstock on July 1, 2011. He couldn't be bothered to look in the general direction of his depressed-seeming bride, never mind aim for her lips.
The inimitable Helen Mirren is either leaning in for a kiss with director husband Taylor Hackford or she's about to nibble crumbs off his beard.
It was one of the few touchy-feely photo ops from the short-lived romance of Kate Hudson and Alex Rodriguez, and it had all the warm fuzziness of a month-old stadium hot dog. Meanwhile, Kate's mom and stepdad suffered their own smooching issues …
Goldie Hawn and Kurt Russell are probably thinking the same thing: This nose-flattening kiss is almost as icky as the kidnapped-amnesiac plot line of "Overboard."
Al Gore's attempt to give Tipper a tonsillectomy at the 2000 Democratic National Convention was a lot like his presidential run against George Bush: unsuccessful. In June of 2010, they separated after 40 years of marriage.
