Demi Lovato Tattoo -- Singer Adds New Ink

Demi Lovato got her entire forearm inked up with flying birds ... Kat Von D did the honors.

From Huffington Post: "Demi Lovato is no stranger to tattoos, but her new ink leaves us feeling a little … flighty. The 20-year-old 'X Factor' judge showed off her new tattoo, a flock of birds 'flying' up her left arm and the word 'faith' written in cursive, on her Twitter page Monday."
