Happy belated birthday to Jennifer Aniston! She celebrated her 39th birthday on the set of her new movie, “Traveling,” this past Monday. Jen’s cast and crew surprised her with a large giant cake — but nobody popped out.

During the past weekend, a source spotted Jennifer and about 20 of her closest friends celebrating by having dinner at Cioppino’s Mediterranean Grill. 

Another little tid-bit for you: Jennifer Aniston’s ex-boyfriend, Vince Vaughn, has expressed his desire to work with her once again:

“Yeah I would, I definitely would. She’s great! I think the world of Jen. She’s a great actress, you never know.”
