London -- Hollywood singer-actor Jessica Simpson, who is pregnant with her first child, is not liking her fat body. The star is desperate to deliver the child and get back to her normal shape. The Blonde Ambition actress, who is due to deliver in the coming weeks, is eager to shed the 40lbs she put on during the pregnancy, Showbiz Spy reported. "I had a great pregnancy. Eating and not having to worry too much about it has been fun. Taking a break from working out has definitely been fun. But I'm ready for it to be over. I'm ready to have my body back! I feel like I could pop at any second," she added.
