Also in Las Vegas: Audrina Patridge, who enjoyed dinner at the Hard Rock Hotel & Casino’s newly-opened restaurant 35 Steaks + Martinis with her brother Mark and on-again beau Corey Bohan. The group headed to Vanity Nightclub next, and the Hills star spent her night dancing with her friends and mingling with excited fans.
