“ The House Bunny” opens in theaters nationwide tomorrow night (August 22), and last night the Mann Village Theatre in Westwood, California was the setting for the big LA premiere.

Everyone from Anna Faris to Emma Stone, Katherine McPhee, and Rumer Willis showed up to promote their latest project, about a Playboy Playmate who gets kicked out of the Playboy Mansion and is forced to move into a sorority house full of social misfits.

Even Hugh Hefner and his Girls Next Door showed up, looking absolutely fabulous, to see what all the fuss was about, along with High School Musical hottie Ashley Tisdale and Entourage star Emmanuelle Chriqui.

But the big news was that Rumer Willis’ entire family was in the house to lend her support. Parents Bruce Willis and Demi Moore along with Bruce’s girlfriend Emma Hemming and Demi’s husband Ashton Kutcher did some red carpet posing before heading inside to see the film.

And of course Rumer’s new boyfriend Micah Alberti showed up to congratulate his sweetie on her sure-to-be-a-hit movie.
