Rumer Willis, the daughter of Bruce Willis and his former wife Demi Moore, has brought together her parents and significant others at the Los Angeles premiere of her new movie, The House Bunny. The role marks the first adult acting job in a high profile project. Demi Moore was joined by her husband, Ashton Kutcher, while Bruce came in with his model girlfriend Emma Heming.

Rumer Willis came to the premiere with her boyfriend actor Micah Alberti. The 20 year old actress, who wore a Reem Acra dress, was also joined by her two sisters and their boyfriends. The self-proclaimed dork and computer nerd thanked for her family's support and said she is grateful for their help.

In The House Bunny, Rumer Willis plays the role of an introvert in a back brace with very low self-esteem, Joanne, who is helped by a former Playboy bunny regain her self-confidence. The flick is written by Kirsten Smith and Karen McCullah Lutz (Legally Blonde). Willis wears a brace through much of the film, and Katharine McPhee dons a fake pregnancy belly. They are both sorority members and are joined by Anna Faris as Shelley Darlingson, a Playboy bunny who gets kicked out of the mansion and who wants to revamp their Zeta Alpha Zeta sorority.

American Idol finalist Katharine McPhee gets the chance to sing two songs, once in a karaoke performance, and doing a modified cover of the Waitresses' 1982 hit I Know What Boys Like for the end credits. McPhee will also soon star in The Storyteller, a psychological drama.

Although she doesn't fit the typical image of a Hollywood celebrity, Rumer Willis has already acted as a child in small roles in a few of her parents' movies, such as Striptease, Hostage and The Whole Nine Yards.
