Eva Longoria is obsessed with "working on her butt".The 'Desperate Housewives' star revealed she sticks to a special exercise regime to maintain her pert derriere.She said: "I love doing squats in the gym. When I do them my butt beefs up and I fill out my jeans better. "I'm constantly working on my butt because of, you know, gravity."The 33-year-old actress - who married basketball star Tony Parker last July - fears it will become harder to keep her bottom in trim after she has had children.She said: "I'm nervous about what's going to happen back there when I have children. I'm full of fear. I don't want anything happening to the butt."Eva has frequently expressed her desire to start a family.
