Demi Lovato is a bit of a sassy lassy. She got to show off her humor in an interview with Y100 backstage at the Jingle Ball in Miami.

She did get slightly serious when discussing her departure from The X Factor. "I wouldn't say 'quitting,'” she clarified to the interviewer. "I'd say 'moving on.' 'Moving on' is a better term. I had a really great two years with X-Factor." She's going to focus 100 percent on her own music in 2014.

Everything other than that was goofy fun, with Demi answering some funky questions, including one asking if she ever read a false rumor about herself that she wished was true. She mentioned a story that listed her last name as "Lavender," which she figured was auto-correct. So we can call her Demi Lavender from now on.

She was also asked to name one product that she wouldn't endorse. "Probably Depends," she answered. The radio interviewer said they would leave that to Jamie Lee Curtis. Demi felt bad, since she loves Jamie Lee, so she changed her mind. "I want to endorse Depends!" Ha! There you have it.

Toward the end of the interview, she dipped into the "naughty" stocking and had to answer this not-so-nice question: "If you were picked to give one celebrity plastic surgery, who would it be and what type of surgery?"

Demi smiled and looked off camera before answering, "I was just talking about this this morning, actually, but I'm not going to say it." What a tease! The interview wanted something, like a Twitter handle or a hashtag, but Demi refused. She quipped, "Hashtag 'I'm not telling you.' Hashtag 'I shouldn't even think this!'" She laughed. "It should be me and I should get a boob job. They're like mosquito bites!"

She thought that "naughty" question was so much fun, she picked another one. Watch the video below for more from Demi, who probably won’t get a boob job or endorse Depends … at least, not yet.
