Party-loving pop star Ke$ha has moved back in with her mom in Tennessee to recover from a broken heart.

The "TiK ToK" singer's career has really taken off in recent months, but it cost her a romance with a guy who turned out to be no good.

Ke$ha says, "My last boyfriend smashed my heart into a million billion pieces."

And she admits her next partner will have to be extra special: "I've had no father figure, and I had finally trusted a man. If I were to get involved with another guy, he'd have to be pretty much the Second Coming."
