The US X Factor judge showed of her new body art to her Twitter followers today with the caption: "Thank you so much @thekatvond for my new ink!! I think it's beautiful and I love it!!"
Kat, who has inked the likes of Lady Gaga and half of America on her shows LA Ink and Miami Ink, was all smiles as she posed for a picture with the 20-year-old in her parlour.
Demi opted for a flock of birds on her arm, bringing her total tattoos to a round dozen, including a feather behind her ear, a cross on her hand and the words "Stay Strong" on her wrists.
The Camp Rock singer/actress, who has in the past suffered with eating disorders and spent time in rehab, has made no secret of the deep meaning of her array of body art.
