Eva Mendes made her breasts bigger for her role in new comic book movie 'Ghost Rider'.The stunning actress stars opposite Nicolas Cage in the new movie as his character's love interest Roxanne Simpson, who in the original Marvel comics had blonde hair, blue eyes and a large chest.Latin beauty Eva was worried die-hard fans of the series would object to her brown eyes and flowing brown hair so made sure her boobs were big enough by gaining weight.She told Maxim magazine: "The original Roxanne was blonde and blue-eyed, but also had huge bajoongas. If I gain weight it goes to my boobs and my butt. I figured since I can't be blonde and blue-eyed, I'll at least have her bra size. So the bajoongas got big. They were out of control!"In the film, Cage plays stunt motorcyclist Johnny Blaze, who in the Marvel universe sells his soul to Satan in order to save the life of his mentor and ends up becoming a vengeful vigilante with a flaming skull for a head.'Ghost Rider' is due to be released in February this year.
