Rumer's Premiere Fan Club: Bruce, Demi and Ashton!

Willis's amicably divorced parents, Demi Moore and Bruce Willis, attended the Westwood premiere of the comedy House Bunny – and both brought along their significant others. (That would be Ashton Kutcher – wearing a suit and scruffy sneakers – and model Emma Heming, respectively.) The exes also escorted their two younger daughters Tallulah and Scout.
"[My family] has always just been very supportive," Rumer told PEOPLE on the red carpet. "I'm very grateful."
Wearing a Reem Acra dress, the budding actress, 20, was joined by her boyfriend actor Micah Alberti, who made small talk with Kutcher before posing for a family photo.
Once inside, the whole family sat together on an aisle in the middle of theater, chatting with friends before the movie started. Papa Bruce, 53 and sporting a white beard, held court at the edge of the aisle while Moore, 45, talked with girlfriends.
The last public appearance of the entire Willis-Kutcher-Moore five years ago – when the whole crew came together for the 2003 premiere of Charlie's Angels: Full Throttle.
