"Yes, it's true, they have broken up," Belle's rep tells MTV News. "There is no third party involved, and they care deeply about each other and will remain friends," MTV.com reports.

The buzz is that Joe was reportedly crying during a Jonas Brothers concert in Detroit Sunday night, singing "Much Better," a song he penned after falling in love with the star of the film 10,000 B.C.

Joe was reportedly so hurt by the breakup that he altered the “Much Better” song lyrics at the concert, changing it from "Get a rep for breakin' hearts, now I'm done with superstars" to "Get a rep for breakin' hearts, now I'm done with movie stars," The Money Times reports.

Though neither Jonas or Belle ever confirmed that they were dating, Jonas was often seen going out to lunch with the 10,000 B.C. actress. The two met last September while filming the Jonas Brothers' music video "Lovebug." Jonas broke up with Swift soon after meeting Belle but made it clear in a blog on the Jonas Brothers' MySpace page, that he never cheated on anyone, People Magazine reports.
