VEGAS, BABY!
Rumer Willis celebrates her 21st birthday Sin City-style with – what else? – showgirls and an Elvis Presley impersonator Saturday at TAO Nightclub at the Venetian. Also joining her at the bash (the day before her actual b-day): mom Demi Moore, dad Bruce Willis, stepdad Ashton Kutcher, younger sisters Tallulah, 18, and Scout, 15, and her Sorority Row costar Audrina Patridge.
