I dunno who is happier!! Teenage girls or Teenage boys about this?!!?

Hannah Montana star Miley Cyrus has split with her teenage boyfriend Nick Jonas.

The singer/actress, 15, and the youngest of sibling trio The Jonas Brothers have been dating since the start of their current sold-out U.S. tour.

But the couple has now parted ways, according to New York gossip column PageSix.

A source tells the publication, "They just broke up, but not many people even knew they were going out."

A spokesman for Cyrus says, "We do not comment on our client's personal life."
