Demi Lovato has hinted she would consider going under the knife.

The "Heart Attack" hitmaker admitted she isn't particularly happy with the size of her cleavage and should get breast implants. When asked to name a celebrity who she thinks needs plastic surgery, the 21-year-old star told Y100 radio station before the Jingle Ball in Miami, Florida on Friday, "It should be me! I should get a boob job. They're like mosquito bites."

Demi, who will not be returning to the judging panel of The X Factor USA next year after two seasons on the show, previously revealed she wants to be healthier in 2014 after learning to love herself for who she really is: "It is so important to me [to take time off]. I think we might do a few things here and there that I've committed to already or that I'm passionate about. When I work so much, I don't get a lot of sleep and I think I really want to get really fit and in shape and just get really healthy. I want to be rested mentally and spiritually - I think it's a month to re-charge and I would love to have more than that but I've decided to go on tour as well."
