Grazer on Prowl?

The Polaroid Beach House was packed this weekend with stellar luminaries like Gummi Bear, a "firecrotch" spewing little person ... and mega producer Brian Grazer?

Amid a crush of twenty-something MySpacers, the recently single 56-year-old Grazer was spotted on the beach in Malibu, showing off his abs while chatting up a hot Aussie in a bikini.

Grazer was spotted last week by TMZ cameras waiting outside the W hotel for Britney Spears and Criss Angel to emerge from their love nest -- with Brian disappointed about missing an opportunity to talk to the magician in person about an upcoming project. Poof.

Expect Grazer to pop up next at Les Deux.
