Jennifer Lopez doesn’t want her husband to see her sex scenes

The actress-and-singer had to film a racy love sequence for new movie 'The Back-Up Plan' – in which she plays a woman who is desperate to get pregnant – but banned Marc Anthony from the set on the day of the steamy shoot.

She said: "I didn't want to torture the poor guy. He shouldn't be watching when I'm seducing another man on a kitchen table. Personally I don't like doing love scenes at all, because they make me feel uncomfortable."

Although she didn't want Marc to see her getting it on with another man in 'The Back-Up Plan', Jennifer wasn't too nervous about baring her body on-screen because she is so pleased with her post-pregnancy figure.

The 40-year-old star – who has two-year-old twins Max and Emme with Marc – didn't go on any fad diets to shift the weight and simply relied on discipline and exercise.

She told website Gala.de: "I worked out a lot. I struggled to get rid of the last 20 pounds. I had to change my eating habits after having the twins. I eat a lot less now than I used to. But I love bread and you're not allowed bread with most diets."
