MILEY CYRUS - IS CYRUS' BITTER BREAK-UP SINGLE ABOUT JONAS?

MILEY CYRUS' new record takes aim at an ex-boyfriend, believed to be JONAS BROTHERS star NICK JONAS.
On her new single 7 THINGS, the teenage pop sensation accuses her target of double dating her, singing "You're vain, your games, you're insecure/You love me, you like her..."
Cyrus and 15 year old Jonas dated secretly while they toured together last year (07), but the romance fell flat at the end of 2007 when the Hannah Montana star went public with her feelings and kissed her then-boyfriend during a concert.
According to In Touch magazine, Cyrus isn't all bitter about her broken romance. After blasting her ex on record, she sings, "And the seventh thing I hate the most that you do/You make me love you."
