X17 XCLUSIVE: Rob Pattinson Parties At The Chateau Marmont!

Looks like "Twilight" hunk Rob Pattinson is really enjoying his time in Hollywood! The 22-year-old actor was spotted drinking (and smoking, tsk tsk) at the Chateau Marmont last night, and it looks like he had a fabulous time.

When it was time to call it a night, Rob covered up his luscious locks with a beanie (sigh) and headed home with his pals (including actor and fellow Brit Tom Sturridge) as well as two ladies. Hmmm, think the girls were just friends, or were they groupies looking to score some love bites?

As Rob and his pals left Chateau Marmont, they appeared to be in a playful mood, but Rob wouldn't answer photographers' questions, which has us wondering what happened to the camera friendly Rob we fell in love with!
