Taylor Swift scribbles song messages on her arm

Taylor Swift has taken to scribbling meaningful lyrics on her arm before gigs because the words help her through tough moments onstage.

The country sweetheart takes to the stage with her lucky number, 13, written on her hand and song lyrics on her arm - and she insists this will become a longtime habit.

The Love Story singer says, "One day at rehearsals I was having a rough day, and I wrote a lyric by my friend Selena Gomez on my arm: 'You've got every right to a beautiful life.' It looked cool, so now I put lyrics on my arm every night (before a show). It's like a mood ring."
