Jessica Biel was terrified about Adam Sandler touching her breasts in their new movie.The 25-year-old actress, who stars alongside Adam in 'I Now Pronounce You Chuck and Larry', worked out for weeks to ensure she looked her best for the scene where the comic actor feels her boobs. Jessica told Style magazine: "I was definitely freaked out about filming that scene where Adam has to inspect my boobs to see if they are natural. I knew it was coming, I thought, 'I've only got a month, three weeks, then two weeks.' "I had to train pretty hard and stay on a structured diet. I don't like the word 'diet' though, I just kept my eating in check to get to a place with my body where I felt, 'OK, its cool, I can be in a movie in my underwear.' "Jessica, who plays a lawyer hired by two New York firemen who are pretending to be gay in the film, admits she loved working with Adam. She added: "I like Adam a lot. He is like a big brother to me. It was such fun doing the movie together."It seems the stunning actress, who is currently dating Justin Timberlake, has got over her shy attitude to on screen nudity. Jessica recently agreed to bare her butt and breasts to play a stripper in new movie 'Powder Blue'.
