Jennifer Aniston jetted to Mexico last week for an early birthday celebration with several famous friends -- including her rumored beau, Gerard Butler. People magazine reported that Aniston, who turns 41 on February 11th, flew Butler, Courteney Cox and Sheryl Crow down to Los Cabos last Thursday (February 4th).

The A-listers were photographed frolicking around a waterfront villa at their Mexican resort.

Aniston has been sporadically linked to Butler since they began filming The Bounty Hunter, which opens next month.
