Gavin Rossdale performed an acoustic set at the Conde Nast Traveler’s Hot List party in Las Vegas this weekend for a starry audience. Chris Evans avoided the line to get in by sprinting up an escalator. Meanwhile, Gavin's wife Gwen Stefani joined him for the event and looked gorgeous in a sheer black top and shorts on the red carpet, showing off a huge smile for photographers. Gavin and Gwen walked the red carpet together, followed by another couple — Kate Beckinsale and Len Wiseman. The British actress looked hot in her LBD, and stayed close to Len inside as they listened to Gavin play. Fun!
