Celeb Sweat: Hottest Spots

Kristen Chenoweth's favorite over-the-shoulder pose shows off her toned back which she keeps lean through running. Her newest gig as Carlene Cockburn, the head soprano in the church choir and Bible blogger, is sparking controversy. ABC's GCB couples Christian values with sinful characters, but there's no dispute that her diet and fitness regimen are on point. She's been spotted on the streets of New York and even participated in the Heel-A-Thon in Central Park. She tells Shape she eats almonds, oatmeal, and drinks tea daily and splurges on 90-calorie cans of Coca Cola to treat herself. Watch GCB, Sundays at 10/9c on ABC. If you'd rather the live version, catch Kristen who's currently on tour supporting her album Some Lessons Learned.

While Eva's reign as a "Desperate Housewife" is almost up, her latest plunging neckline is sure to keep her in the spotlight. While she tells Health Magazine she'll travel everywhere after shooting wraps, we're hoping her dresses don't go too far. The petite actress hates jogging and all things cardio, but her degree in kinesiology is proof of her commitment to working out. She skips the elliptical, but loves weight training and abs. She and Mrs. Obama might be gym partners in the coming months, she's been very vocal about the upcoming presidential campaign and is one of the national co-chairs for President Obama's reelection campaign.

Carrie Underwood has been a vegetarian for over seven years, but the American Idol winner and country music superstar just dropped a few more animal products saying she's now 95 percent vegan. Dairy and cheese aren't good enough for Carrie's well-defined legs. She tells Self magazine, "My veganism is based on a concern about where my food is coming from." True to her small town roots, (shoutout to Checotah, Oklahoma!), she hasn't ruled out running Underwood farm. "I'll never eat meat again, because I look and feel better without it, but If I could raise my own cows and chickens and produce my own eggs and cheese, it would be awesome! The food would taste better, because the animals would be happy!"

Singer Debbie Gibson is a new contestant on Celebrity Apprentice and the 41-year-old is looking like a million bucks. She says she has never gone into anything half-hearted and we can see that she gives her all in the gym. Whether it's sit-ups, planks, or leg raises, it's working well, as evidenced by her six-pack abs. Best known for her #1 Billboard hit, Foolish Beat, for which she, at 17, became the youngest person to write, produce and perform a number one single. She points to her 25 years in the entertainment industry as well as stamina, a sense of humor and a backbone for her teen-stardom survival. As the new spokesperson for the charity, she's playing to help Children International. If you're busy Sundays at 9/8c you'll miss Celebrity Apprentice, but she'll be on the Tonight Show with Jay Leno for your viewing pleasure tonight!
