Demi Lovato cannot catch a break. The “Heart Attack” singer is once again involved in a leaked picture scandal after nude photos, allegedly of her, hit the web late last week.

The sexy and explicit photos, which were published Egotastic!, a website that focuses on sensual celebrity snapshots, has Lovato showing off her breasts, side tattoos and backside in various angles.

The package of photos also includes various photos of Lovato, 21, with her on-again, off-again boyfriend Wilmer Valderrama. The couple is seen hugging and kissing in bed, but the real sassy photos are just of Lovato.

After the alleged pictures went online, Lovato fought back with a strong statement on her Twitter account.

Pictured with a fighting face and wearing what looks like boxing gloves, the former "X Factor" judge wrote in Spanish: “I am strong. I am a fighter. So don’t underestimate me.”

The former Disney star was the subject of another rumored nude photo leak last year when photos allegedly of her were being shopped around for the highest bidder.

The photos, which were teased by Celebslam, reportedly showed a dark-haired woman who looked like Lovato in compromising positions, including nude in a bathtub, lying topless in bed and leaning in to kiss another woman.

The seller reportedly said in emails to Celebslam and Radar Online that the pictures were Lovato, and many of them showed parts the singer is known for, specifically her tattoos. 

The photos hit the web in late August, but were never confirmed to be Lovato.
