She’s certainly a creature of habit – and why change a good thing?
Jennifer Aniston headed to one of her favorite getaway spots, Los Cabos, Mexico, where the actress is getting a jump start celebrating her 41st birthday – Aniston’s big day is actually Feb. 11 – with a group of friends. But this year, she had a surprise birthday guest: Gerard Butler, her costar in the upcoming comedy, The Bounty Hunter. Last month, the two were spotted laughing and spending a lot of time together at the Golden Globes.
Aniston flew a large group of pals including Butler, Courteney Cox, her husband David Arquette and Sheryl Crow, whose birthday is also Feb. 11, to the One & Only Palmilla resort Thursday evening where the group is staying in a beautiful waterfront villa.
