Demi Lovato has a new Tattoo.

The 'Skyscraper' singer posted a picture on her twitter account of the inking of the word 'faith' on her right forearm with the message "Sometimes you just gotta have a little bit of... (sic)"

However, Demi - who has the words 'stay' and 'strong' tattooed on her wrists - initially didn't tell her father about the latest addition to her collection.

Her friend Lauren Martin tweeted: "I take it your dad knows now? #bestiez"

Demi, 19, replied: "Hahahaha he does... He found out when I performed tonight and I showed up on the jumbo trons... (sic)"

The former Disney starlet - who was admitted to rehab in November 2010 to receive three months treatment for an eating disorder and self-harming - got the designs on her wrists to make sure she doesn't forget what she has overcome.

She has previously said: "I think scars are like battle wounds-beautiful, in a way. They show what you've been through and how strong you are for coming out of it. My tattoos say 'stay strong' - 'stay' on one wrist and 'strong' on the other. Now I'm able to look at them and be thankful for being alive. I think that I've been blessed over the past year to be able to start over."
