After shedding all of her baby weight, a slimmer-looking Jennifer Hudson said she will be the newest celebrity spokesperson for Weight Watchers, RadarOnline.com has learned.

The Oscar and Grammy-winning star appeared on Good Morning America Thursday to talk about the pounds she has dropped since she gave birth to her son David Jr. on August 10, 2009.

“I decided to do Weight Watchers” Hudson, who has lost all of her baby weight, said. “I feel like I’ve conquered the world … no one recognizes me anymore; I wanted to go in a different direction and find a better lifestyle.”

Hudson said that losing the weight was not for show business, but rather family.

“I was very comfortable with myself before,” she said. “I have a child now and I want to set a great example for [my son]. Make better life choices, health choices, and just create a good example for him growing up.”

Weight Watchers has afforded Hudson a much healthier lifestyle, she said, because she can eat whatever she pleases, as long as she stays within her plan’s point limits.

“I’ve just reached a new milestone,” Hudson said. “It’s about the progress and being comfortable.”
