Uhhh, whoa. The Kendra Wilkinson/Holly Madison war hit the NSFW stratosphere after the "Kendra on Top" star as she unloaded on her former housemate on Twitter on Thursday.

The tweets were so outlandish that even Kendra realized that perhaps she went overboard and deleted them.

"I know my recent posts were a little over the top and I apologize for that," she said after her posts were up for several hours. "Sticking up for me n my beliefs is hard for me at times. Sorry."

The two former "Girls Next Door" stars have been at odds for years, with Holly speaking often about her disdain for both Kendra, Playboy founder Hugh Hefner and life in the famous Playboy Mansion. Kendra has been anything but silent about her legitimate hatred toward Holly.

The latest in the war of words comes after an interview Holly gave to People magazine where she claimed she was fearful of her life within the walls of Hef's wonderland.

The tweets were shocking, sexual and rated XXX.

The two women rose to fame as two of Hugh's three live-in girlfriends on "The Girls Next Door." Last year, Holly blew the lid off Playboy life in her memoir "Down the Rabbit Hole: Curious Adventures and Cautionary Tales of a Former Playboy Bunny."

"The only thing he ever gave me is a little bit of fame," she wrote. "Fame is not always worth it."

In the book, she alleges that life in the mansion was one that involved drug use and backstabbing. At one point she claimed she was so miserable that she contemplated suicide.

Holly has maintained that everything she has said is true, even claiming Hef promised her $3 million if she stayed with him.

"Hef and I started hitting kind of a rocky patch when it became clear that Bridget [Marquardt] and Kendra were leaving, they were moving on to new things," she told Oprah Winfrey during a "Where Are They Now?" special. "I just had enough and just realized all these delusions I'd been under and that this was no longer the life for me."

Kendra has claimed the book is "full of lies."

"Someone needs to have a voice against this. Hef won't do it. He's too nice of a guy," Kendra said last year. "It's just weird how someone can get away with such a thing."
