Christina Aguilera is back, and she's hotter than ever after her unbelievable 40-pound weight loss. Aguilera wowed fans with a sizzling performance of her new single "How I Feel" on "The Voice" Nov. 4.
"No, that's not your imagination. She looks great, she feels great!" remarked Maroon 5 Frontman Adam Levine, a judge on "The Voice."
This isn't the first time Levine has commented on Aguilera's weight. Last year, he chivalrously defended Christina against fat-shaming weight bullies.
"It's a very basic thing: She should be left alone," said Levine, who was named the 2013 Sexiest Man Alive.
No one should bother or haggle her about her weight or anything that she does or says. People shouldn't say those kind of things because, f- you. It's like, come on guys, grow up.
The one thing about the culture right now, celebrity culture particularly, is people feel like they can just say nasty things about other people, whether it's Christina or whether it's me."
While Aguilera has not said exactly how much weight she has lost, fitness experts estimate the blonde beauty has shed 40 pounds since April 2013. Christina credited a low-carb diet and yoga workouts for her stunning weight-loss transformation.
Christina, 32, has long brushed off fat-shaming comments, saying they don't bother her, but admitted that working out makes her feel great.
In May 2008, Aguilera lost 40 pounds just four months after giving birth to son Max by combining cardiovascular workouts and weight-lifting for 90 minutes a day, five days a week, and following a high-protein diet.
"I feel a sense of accomplishment," she said. "As you feel your body getting stronger, you become more motivated to be in the gym! It doesn’t matter how big or small you are. When you’re defined, it’s sexy. I exercise because it makes me feel good. It’s not just a physical thing."
