There's Ashlee -- Where's Her Petey?

Ashlee Simpson and raccoon-eyed Pete Wentz have been spotted together three times this week -- but last night Ash went out solo.

The couple were seen in Las Vegas and L.A. this week, but Ashlee arrived alone to the opening of Runway Nightclub in New York, having dropped Petey somewhere else earlier in the evening. Taye Diggs also went to the club's opening -- arriving with a hot, non-Idina Menzel blonde.

Meanwhile, "to the left" coast, TMZ spotted Michelle Rodriguez, a lounging Joey Fatone, Alfonso Ribeiro, Borat's buddy Ken Davitian and a chatty-tatty Dennis Rodman.

All this and more in today's "Where's Petey?" bicoastal Star Catcher.
