In foto of Demi Lovato that hit the Net, the Disney stella, star is seen pulling her camicia down to reveal her cleavage, surrounded da a group of her friends, and also posing in just a bra.

While the foto were published on the blog Anything Disney on Wednesday, other websites just picked them up Friday (December 17). Anything Disney postato an additional foto of Lovato, reportedly from the same night, where she is wearing a belly-baring top, pulling down her camicia and licking a female's face.

One of the women in the photos, donning orange/red hair and baciare Lovato's shoulder, appears to be Alex Welch, the dancer Lovato allegedly punched before the singer/actress entered a treatment facility last month.

Recently, Welch opened up about her incident with the teen star, noting that she was surprised when Lovato allegedly struck her. "I felt, honestly, I didn't say anything and didn't think twice about it," Welch recalled. "We were on the plane with the Jonases having this awesome time, and I didn't get a call o text from Demi o a 'Hey, te got a problem with me,' nothing. And she walks up and punches me and, literally, walked away and got in her seat. No one should walk up and do that and brush it over, it's not right."
