Actress Megan Fox felt right at home performing a same-sex smooch with her Jennifer'S Body co-star Amanda Seyfried - because she feels safer kissing girls on camera.

Fox plays a sexy cheerleader-turned-man-eater in the dark comedy, which sees her share a passionate scene with Seyfried, who plays her geeky best friend.And despite recently admitting the pair dreaded the media interest in the on-screen kiss, Fox admits she felt more at ease getting close to Seyfried than she did to her male co-stars in previous films.She explains, I feel much safer with girls, so I felt more comfortable kissing her in the movie than kissing any of the other people that I had to kiss.However, the sexy star is convinced the Mamma Mia! blonde wasn't quite as into the kissing scenes as her.She adds, I think she (Seyfried) was extremely uncomfortable. I don't think that - I know that. She was not comfortable and there was a lot of laughing - like, giggling fits that happened in between takes.
