The Voice coach Christina Aguilera is shrinking. And now some are wondering if the star’s skinnier body is the result of hard work…or plastic surgery.

Aguilera stunned the audience when she debuted her fit figure on Jay Leno’s Tonight Show Wednesday. The singer said that she feels good about her continued weight loss and sexier than she ever has.

"I'm 32, and I feel sexier than ever, just because you know what you want,” she said.

But amidst her big reveal were also whispers that Aguilera may have gone under the knife to achieve her new look. What do you think?
