Hudson has had her share of weight ups and downs. Dubbed "the big girl" as a contestant on season 3 of "American Idol," she transformed her body for her Oscar-winning turn as Effie in "Dreamgirls" by gaining more than 20 lbs. She signed on as a Weight Watchers spokeswoman last year and has since gone from a size 16 to a svelte size 6.

"I'm in the best shape of my life!" she recently gushed to People. Still, she admitted, "In my head, I am still the same weight I was before, It takes a while to get used to it." But one thing is certain. Said Hudson, "This is the way I want to be and the way I want to stay!"

Hudson released her sophomore album, "I Remember Me," in March. The set has sold 338,000 copies, according to Nielsen SoundScan.
