Another major red carpet moment for Jordin Sparks.
The Season Five American Idol victor, 22, showed off her incredible 50-pound slimdown at the USTA's US Open Opening Night Gala in NYC Monday night in a skintight, crochet white dress and nude heels.
On the red carpet, Sparks -- who wowed gala attendees with her performance of the National Anthem -- opened up to Us Weekly about staying in shape despite the demands of her jam-packed schedule.
Sparks, usually a gym buff, admitted she hasn't had as much time as she'd like to fit in workouts while she travels the country promoting Sparkle. "It's been so crazy . . . that's where really watching what I eat comes into play," she explained.
"I've been trying to stay away from all of the stuff at the airports, because that's where I've been living," the pop star, who debuted her new figure last year, shared. "I've been trying to eat a lot of salads, apples, fruits -- I've been trying to stick with things like that so I can snack on those instead of being like, 'Oh look, a bag of chips! I'll just have those!'"
Though she does her best to nosh on healthy fare, Sparks admitted she lets herself indulge when she finds herself facing a serious craving. Her favorite feast?
"In-N-Out burger, for sure!" she told Us. "Well, that, or my mom's sweet potato casserole. It's a good thing she only makes that once a year because I would eat it all day long!"
