Celebs party in Vegas for New Year’s

Newly single Rihanna returned to the States after her Christmas homecoming to Barbados and brought in the New Year in Vegas. While rocking this red and sheer striped dress, Rihanna hosted a shindig at Pure Nightclub at Caesars Palace Hotel and Casino and led the countdown to midnight.

Holly Madison took charge of the festivities when she hosted a New Year’s Eve bash at Lavo at the Venetian.
