A slew of racy new photos of "X-Factor" judge and singer Demi Lovato have been offered for sale to Radar Online, though the gossip site has not been able to verify that they are authentic. If they are verified and leaked online, will Lovato's career be compromised?

Over 20 naked images of Demi Lovato (or possibly a look-alike) were emailed to Radar last week, featuring the star posing nude in a bath tub and lying topless in bed among other sexy poses. The photos were taken sometime this year, as they feature Lovato's signature black birds tattoo on her arm, though it is unclear of how the source uncovered the private images.

"These are Demi," the source and photo supplier confirmed to Radar. "The collection I have show some nude, including face, some including parts of the body Demi is known for - tattoos, butt, chin."

Lovato has a total of 12 tattoos all over her body, including on her wrists, hands, feet, side, shoulders and behind her ear. If Radar is able to confirm that the naked photos are real, the tell-tale tattoos could be part of the proof.

However, so far Radar has opted not to publish the racy pictures, as they could very well compromise the young star's career. This fall, Lovato will reprise her role as a judge and mentor on "The X-Factor," and will return to acting on another hit FOX show, "Glee," playing a struggling artist and friend of Rachel Berry (Lea Michele) who is part of a major story arc for Santana and Rachel's characters.

While it is unknown if Lovato's leaked nude photos were the result of a phone hack or simply found their way online through a friend (or boyfriend), neither Lovato nor her rep responded to Radar Online for comment after they were notified on Friday. Is this a PR move, or were these pictures sent out with Lovato's permission?

Meanwhile, Lovato is currently in Kenya for her 21st birthday, tucked away from Hollywood and the spotlight as she does charity work for the international children's rights organization, Save the Children.
