Demi Lovato's dad stunned by new tattoo

Singer Demi Lovato shocked her dad by accidentally revealing a brand new tattoo during a concert in Pennsylvania on Thursday (07Dec11).

The Skyscraper hitmaker took to the stage at the Wells Fargo Center to perform as part of the Q102 Jingle Ball in Philadelphia and while belting out one of her signature tunes, she gave the camera a quick glance of the word Faith, inscribed across her forearm.

However, the star failed to tell her father about the body art and he found out at the same time as the rest of the audience when the image popped up on the arena's jumbo screen.

Responding to a Twitter.com follower about her parents' reaction to her latest ink, she wrote, "Hahahaha... He found out when I performed tonight and I showed up on the jumbo trons."
