Christina Aguilera is back and looking better than ever! The 32-year-old blonde with the golden pipes is making a brilliant return to her coaching chair on The Voice. And it looks like Aguilera might be this season’s sexiest coach. Sorry, Blake, Adam and Cee Lo!

After months of strict dieting and excruciating workouts, Aguilera now gets to show off her hard work in a bandage dress and a pair of pumps during Season 5 of The Voice. The leggy singer even gave fans a sneak peek of her transformation during a promo for the NBC singing competition. There Aquilera showed off her tight and toned physique in a skin-baring dress.

But how exactly did the Season 5 Voice coach get so skinny? Was it a liquid diet? Or perhaps an aqua cycling class? Nope, it was actually haters who helped this vixen reclaim her fabulous figure. According to Us Weekly, Aguilera dropped the weight after a slew of body critiques mocked her fuller size.

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

Little did Aguilera’s haters know that she’s a “fighter.” The singer decided to enroll in a delivery diet program, which offers several nutritious food options like pumpkin-apple quinoa oatmeal, chopped grilled steak salads, and even ahi tuna! Our mouths are watering just thinking of it.

As Aguilera watched what she ate, the starlet saw the pounds melts off. But her slim shape isn’t all attributed to her 1600-calorie-a-day diet — exercise also played a crucial role in Aguilera's slim down. “She’s been working hard — she wants to lose a bit more, but she feels great,” the source continued. “It’s more of a mind-body thing for her. She believes in exercise that she enjoys, doing strength work as opposed to intense cardio.”

We can’t wait to see the sexy, confident Aguilera strut her stuff on The Voice stage in Season 5! “Everyone on set is really happy for her,” an insider from NBC TV show revealed. “Show execs hope her new look will spark viewers’ interest in her again, and get people tuning in. Christina’s weight is giving her a fresh start.”
