Think before you ink, Demi Lovato!

During an appearance on "LIVE! With Kelly and Michael" on Sept. 5, the "X Factor" judge admitted she's beginning to regret getting 12 tattoos in her teens. Pointing to a drawing of her friend's lips on the inside of her left forearm, Lovato called the tattoo "a spur of the moment, stupid decision."

Lovato, 20, has even considered getting her tattoos removed. "I've thought about it before because, you know, when I get older I don't know if I want to have 'rock and roll' on my middle finger," she explained. "But I'm young and I can rock it now. When I get older, I can worry about it later."

The "Give Your Heart a Break" singer also dished on her ever-changing hair color, which is currently blonde. "I think this is my favorite right now," Lovato revealed. "Just because, you know, it's the color I have right now and I don't feel like changing it."

During the interview, Lovato was also asked about what it's like sitting at the judges' table with Simon Cowell, 52, on the "X Factor" (premiering Sept. 12 at 8 p.m. EST on FOX).

"I'm a Southern girl who speaks her mind," Lovato said of trading barbs with the acerbic Englishman. "If you're going to dish it, you might as well be able to take it."
