Actor/director Jon Favreau insists the rumoured romance between best pal Vince Vaughn and Jennifer Aniston is pure fiction because he had "first dibs" on the actress when they teamed up on Friends.

Favreau, who played Courteney Cox's boyfriend PETE BECKER on the sitcom in 1997, reveals he fell in love with Aniston before he married JOYA TILLEM (corr) in 2000 - and, as a result, pal Vaughn can't romance her.

He explains, "I met her 10 years ago on Friends and I called dibs on her at that point, so, whatever you might think, he's such a good friend that he's just keeping an eye on her.

"I'm keeping her on ice, I'm married now... (I want to ) keep her on the side."
