Adrian Grenier Hangs With Pretty Brunettes (And One is a ‘Twilight’ Star!) (PHOTOS)

Adrian Grenier was at the STK third anniversary dinner in Los Angeles Tuesday night, and the Entourage star was never hurting for his own female entourage. The actor, looking hot in jeans and a grey tee, was photographed leaving the restaurant with a mystery brunette by his side.

However, she wasn’t the only pretty girl Adrian hung out with.

He also chatted with Twilight star Ashley Greene inside! As friends though.

Despite some reports alluding to the fact Adrian was there with Ashley (the two were linked back in 2009) or that she may dating Zac Efron after hanging out with him over the weekend, Celebuzz is told Greene is currently single and “happy as ever” post split with Joe Jonas.

But Adrian…are you off the market?
