Rumer Willis stepped out last night to celebrate her role as the newest cast member in the off-Broadway production of ‘Love, Loss & What I Wore‘ in New York City.

Parents Bruce Willis and Demi Moore, who have been called one of “Hollywood’s happiest divorced couples,” were there to congratulate their daughter. Although the couple arrived separately with their spouses (Emma Heming and Ashton Kutcher, respectively), the proud dad and mom were all smiles as they happily posed for pictures with their daughter.

This is far from Willis’ first stab at the family business. The 22-year-old actress has also appeared in ‘Sorority Row,’ ’90210′ and ‘The Secret Life of the American Teenager.’
