Making the short trip from Los Angeles to Mexico, Cameron Diaz and Alex Rodriguez enjoyed a day by the pool in the south of the border locale on Sunday (December 19).

The "Knight & Day" actress proudly showed off her bikini body in a black two piece as she joined her Yankees slugger beau and his kiddies for the holiday getaway.

The trip down south comes as Miss Diaz recently returned to the States following an overseas press tour for her upcoming movie "The Green Hornet".

Due out in theaters on January 14th, a synopsis of the film via IMDB reads: "By night, debonair newspaper publisher Britt Reid fights crime as a masked superhero known as The Green Hornet. At his side is martial arts expert Kato."
