Gerard Butler to Jennifer Aniston: Happy Birthday!

Jennifer Aniston celebrates her 41st birthday with her Bounty Hunter co-star (and close pal) Gerard Butler in an exclusive beachside villa in Cabo San Lucas, Mexico on Saturday (February 6).

Gerry arrived a few of days after the other guests but they all celebrated Jen‘s birthday at Aquos restaurant, which is part of the luxurious One & Only Palmilla Resort.

The twosome was seen scoping out paparazzi with binoculars and a telescope alongside pals Courteney Cox, David Arquette and Sheryl Crowe.
