What never officially existed is now apparently over. Attention tweens of the world—Joe Jonas is now back on the market.

According to Us Weekly, the Jonas Brothers performer and his country singer girlfriend are now over. Sources claim the 19-year-old broke up with Taylor Swift last Friday over the phone.

Back in August, the couple were seen double-dating with Nick Jonas and his girlfriend, Selena Gomez. The two (as pictured above) even sat next to each other - in public - at the 2008 Video Music Awards.

While I’m sure Swift could easily find another man soon, Joe supposedly broke the 18-year-old’s heart. Sounds like good material for a new album!
