Caught in the Act!
Tao Las Vegas turned three years old, and Ellen Pompeo was there celebrating a milestone of her own: her first wedding anniversary with hubby Chris Ivery. The Grey's Anatomy star shared the double celebration with Kate Walsh and her husband Alex Young. (Walsh held her bachelorette party at the Vegas venue.) The stars hung out at their own VIP table, and were joined by the Office's Jenna Fischer. Also having a time out: Lindsay Lohan and Amanda Bynes, who sipped water and danced all night.
Lauren Conrad, hanging out with ex-roommate Audrina Patridge at BondSt Lounge, inside L.A.'s Thompson Hotel. The two were sharing drinks and chatting as the Hills cameras rolled.
A solo Usher, hanging out at Shrine at MGM Grand at Foxwoods after his concert. The R&B star sipped on pineapple-cranberry juice and listened as DJ Chachi played a medley of his tunes for the crowd. Usher even danced in his seat a little – much to the crowd's delight.
Hilary Duff, picking up some clothing during a visit to Intermix in New York's SoHo neighborhood. The starlet grabbed a pair of Theory pants and some Elizabeth and James leggings during her visit to the store.
Will Ferrell, sharing lots of laughter – and some sake and beer – with seven friends during dinner at Nobu West Hollywood.
