Christina Aguilera shows off dramatic weight loss at Television Critics Association event

Christina Aguilera silenced last year’s fat-shaming critics by showcasing her 20 lbs weight loss in a pink mini-dress at a NBC press event in Beverly Hills on Saturday.

Christina Aguilera, 32, looked confident and drop-dead gorgeous in the tiny cleavage-baring frock, which slightly fanned out at the skirt.

The four-time Grammy winner paired her slim new silhouette with platinum waves, a very dark tan, and Christian Louboutin heels.

Christina Aguilera shed the weight thanks to the 1,600-calorie Fresh Diet premium meal-delivery plan, yoga, and regular sessions with trainer Tee Sorge.

“She did it all on her own,” an insider told Us Weekly last month.

“A lot of people were on her about her weight and it depressed her. She went through a bad time because of the criticism.”

A friend of Christina Aguilera’s revealed that she still “wants to lose a bit more”, but “she feels great”.

She joined The Voice‘s Adam Levine, CeeLo Green, and Carson Daly for the Television Critics Association event at the Beverly Hilton Hotel.

Christina Aguilera addressed her absence last season, which was filled by Columbian pop star Shakira.

“Thank god for Shakira, she did a beautiful job, she has sweet, lovely energy,” Christina Aguilera told reporters.

“I cannot live in front of the camera 24 hours a day. I have to take breaks and stay connected with myself…When the cameras go off, I put on sweats and a T-shirt and I’m mom. [My son Max] starts kindergarten in the fall so I’m excited about that.”

Auditions are already underway for the NBC singing competition’s fifth season – premiering September 23.

And The Voice producers are also reportedly pleased with Christina Aguilera’s recent weight loss.

“Show execs hope her new look will spark viewers’ interest in her again and get people tuning in,” a show insider told Us Weekly.
