Christina Aguilera slim: The singer has noticeably lost weight recently, culminating with an appearance at the Time 100 Gala.

Aguilera has been eating healthier and working out at her home gym, according to People. That includes “exploring new methods of exercise” with different trainers, says a friend of the singer’s, including weight training with fitness expert Tee Sorge.

Aguilera was at the New York gala because she was named to the Time 100 Most Influential People in the World list. She was sporting a long black Victoria Beckham dress.

Celine Dion, a fellow singer, wrote a congratulatory post for Time in honor of Aquilera.

“The first time I heard Christina Aguilera sing, I was totally blown away,” she wrote. “I love the way she sings. Her tone is beautiful, and her voice has got so much power, yet so much sensitivity—and technically, I think, she’s flawless.”

“Without a doubt, she’s one of the most talented artists the world has ever seen and heard, and I think she’s going to continue to amaze us for many, many years to come,” Dion added.
