Hey girls!
Rob turned 23 yesterday and TWIST has the deets on how this super-star celebrated!

After filming New Moon in Vancouver during the day, Rob hit the town at night with his friends and co-stars! Rob started the celebration at Glowbal Grill & Satay Bar with friend Sam Bradley. Sources report that Kristen Stewart arrived a bit later, adding that Rob spent most of his time with K-Stew!

"Throughout the evening, Rob definitely chatted with Kristen the most, despite the fact that other New Moon cast members attended the party," the source reveals.

Ashley Greene and New Moon newbie Jamie Campbell Bower also joined in on Rob's b-day festivities! Plus, near the end of the night, everyone sang him "Happy Birthday" -- so sweet!

TWIST girl, does Rob's b-day party sound like fun? Do you wish you were there?

Hugs,
Kourt
