Demi Lovato is a warrior, and she's got the ink to prove it.

In celebration of her just-released album, Demi, Lovato shared a picture of a new shoulder tattoo with the phrase "now I'm a warrior." It's a nod to the emotional track "Warrior" off her fourth studio album.

Lovato appeared on "Late Night with Jimmy Fallon" on Wednesday and explained the inspiration behind her 12th tattoo, her first since she inked a flock of birds on her forearm.

"I have a song on my album called 'Warrior,' and it's a very, very meaningful song to me," she explained. "It's really heavy, the lyrics, but it's an inspirational song as well. ... It was kind of like a tribute to releasing an album, as well as overcoming some really, really difficult things in my life."

In the song, Lovato sings "I've got shame, I've got scars that I'll never show/ I'm a survivor in more ways than you know."

On the day of her album release, Lovato sat down for "Demi Lovato: Live From MTV" and said the track "speaks to her emotionally." But "Warrior" isn't the only song that shows Lovato's vulnerable side; the entire album is filled with honest emotion.

"There are songs that are pretty self-explanatory on this album, and when I played those songs in front of other people I almost felt, like, naked," Lovato said. "There were several times I had to leave the room."
