Jennifer Hudson's Glowing After Baby and Pregnancy

Hudson, pictured here at the Grammy's, revealed her sleek new physique on "Good Morning America," and the 28-year-old looks radiant.

She remarked upon her transformation, saying "No one recognizes me anymore. I wanted to go in a different direction and find a better lifestyle."

Like many new moms, after her pregnancy, Hudson was concerned about her post-baby body. She opted to start the Weight Watchers program, for which she is now the spokesperson.

The star claims she feels empowered by her weight loss, which she achieved by eating controlled portions of healthy foods that left her satisfied.

So how was she able to stay strong? The sexy songstress actually used an iPhone application that tracked her "points," according to "People."

We think the Oscar-winner looks phenomenal. She now joins the ranks of other successful Weight Watchers alums, including Jenny McCarthy, Lynn Redgrave and Sara Ferguson, who all slimmed down on the progam.
