Jennifer Hudson feels like a new person since her weight loss.

The singer and actress has gone down from a size 16 to a size 6, and loves her new figure.

“It’s almost like there is a new person,” she said.

“But there is still the question of how do I want to represent myself, how do I want to be perceived.”

ShowbizSpy reports that her new diet song, Feeling Good, will appear in Weight Watchers’ new ad campaign launching on Dec. 26.

“Basically [the song] is the perfect way to describe this journey and how it’s left me feeling,” Jennifer said. “If I could bottle everything inside me and tell others to help motivate them, then this is it.”

“It’s one thing to lose weight,” she said, “but it’s another thing to eat healthy.”
