London, Feb 08 (ANI): Gerard Butler and Jennifer Aniston have been spotted getting cosy by a poolside in Mexico.

The '300' actor has flown to Los Cabos to celebrate the 'Break-Up' actress' 41st birthday on February 11.

Aniston was dressed in a bikini, sharing an intimate moment with Butler, at their private pool.

A source close to the pair revealed the beauty has been considering a relationship with Butler for ages.

She's gone out her way to spend as much time with him as possible, the Sun quoted the source as saying.

The insider added: It even helped dictate her work schedule. Him turning up in Mexico is a good sign. If she is inviting him to hang out with her closest friends they must be getting serious.

Her friends were worried Gerard was a bit too much of a lad too. But it seems she is taming him.

Aniston apparent plans to celebrate her birthday with her closest pals, including 'Friends' co-star Courtney Cox. (ANI)
