Jennifer Hudson: Being skinny, it’s a job!

Jennifer Hudson is refusing to have another baby — because she doesn’t want to gain weight! Sources say the Oscar-winning American Idol star — who is already mom to 16-month-old David Jr. — has told fiancé David Otunga that he’s going to have to wait to have another child.

Jennifer  has dropped 80 pounds since signing on as a spokesperson for Weight Watchers in April and has gone from a size 16 to a size 4.

“Jennifer has finally got the body she’s dreamed of and knows how much it took to get back and stay in shape after the birth of their son,” a source told American tabloid the National Enquirer.

Jennifer Hudson recently revealed that she loves getting compliments about the way she looks.

“I look younger now than in high school! Hearing how great I look never gets old,” she said last month.

“Being skinny, it’s a job. It’s not easy. I feel this responsibility to the world now — people are watching, so I have to keep going in the right direction in terms of my weight loss. They are using me as a role model, and that keeps me inspired.”
