Villa was boy band central last night -- with JC and Lance from *NSYNC and the Brothers Lachey from 98° all in the house to celebrate Joey Fatone's 31st birthday. Cue the dance-off!
The boys talked asteroids, in one of TMZ's finest interviewing moments. Nicollette Sheridan and Steve Martin were caught -- not together -- dodging paps on Robertson Blvd., while Forest Whitaker did some shopping at Fred Segal. In NY: Lindsay Lohan had a late dinner at Cipriani, and Sienna Miller chowed down at the Waverly Inn with boyfriend Rhys Ifans.
