Demi Lovato is showing just how far she has come since her days of struggling over her body image, even going so far as to make a joke at her own expense over how she looks!

She joked at Y100’'s Jingle Ball 2013 in Miami last Friday (Dec. 20) that she should get surgery to make her breasts larger. During an interview with Y100's Mack backstage at the BB&T Center, Demi was prompted to choose a question from either the "Naughty" or "Nice" bag.

Clearly in a playful mood, she went for "Naughty" and was asked, "You were picked to give one celebrity plastic surgery. Who would it be and what type of surgery?"

"I was just talking about this this morning actually, but I'm not gonna say," Demi responded, laughing. Mack tried to get the answer from her -- even just a hint, Twitter handle or hashtag. She giggled as she answered, "Hashtag I'm not telling you. Hashtag I shouldn't even think this."

Still laughing the whole time, she gamely turned the focus on herself. "It should be me!" she joked. "I should get a boob job. They're like mosquito bites."

So Demi ended up playing "Nice" after all, without dissing another celeb. Watch the whole clip above!
