Joe Jonas stepped out in Studio City, Calif., Friday just as thousands of teenage girls everywhere were anticipating the release of his first solo single!

Joe co-wrote "See No More" with Chris Brown, which debuted yesterday on Chicago's 96.3. It tells the story of a man dealing with a broken relationship -- something the 21-year-old knows something about. His long list of exes includes Taylor Swift, Ashley Greene, Camilla Belle and Demi Lovato.

But even though Joe's gone solo, he hasn't forgotten his brothers, Nick and Kevin. Joe told the radio station:

    " ... having my brothers' support in this whole project is the biggest thing for me ... Being onstage by myself ... will be different for sure. I know there's going to be that little bit of jitters ... "
