She’s the new coach on The Voice, but all eyes are on her impressive body during each episode of the popular singing competition. In just a few months, Kelly Clarkson has undergone an extreme weight loss and she couldn’t look better. During a recent appearance on The Tonight Show in late February, she looked like a different person than the one viewers saw earlier in the day when the pre-recorded blind audition episodes of The Voice began airing.

“Kelly looks like she’s lost 40 pounds!” fitness coach Nadia Murdock Fit told Life & Style magazine. “You can definitely tell there was a dramatic weight loss.” Inaugural American Idol winner Kelly, 35, has battled weight issues for years, especially since giving birth to daughter River Rose in 2014 and son Remington in 2016. But she’s embraced her body type, and revealed last year, “when I’m fat… I’m happy.”

Still, Kelly recently decided it was time for a change. “She started losing weight four months ago,” a source revealed. “She’s been working out with a trainer four times a week.” Kelly has turned to experts to help with her diet, too. “I don’t cook,” she confessed. “We have a chef and her name is Lisa and she makes these amazing things.” Amazing — and healthy. “Kelly has cut back on junk food,” the source added. “She’s been living on a high-protein diet and has swapped sugary treats for raw vegetables.” Sounds like a lot of hard work and sacrifice — but as Kelly has said, “what doesn’t kill you makes you stronger.”

It’s great to see Kelly taking control of her health. The singer revealed last year how she was cruelly fat-shamed while competing on Idol. “Even on American Idol I was really thin, but I was bigger than the other girls on the show, so people would say things to me,” she told People. “But luckily I am super confident, so I’ve never had a problem with shutting people down and saying, ‘Yeah, you know, that’s just what I’m rocking. It’s fine.'” Good for you, Kelly!
