At one of the recent Jonas Brothers concerts, an inside source said Joe looked visibly upset when he sang "Much Better", a song he penned after he began dating Belle last fall. The song is about a girlfriend who is "much better" than a previous girlfriend.
The 19-year-old pop star made headlines when he broke up with Taylor Swift to date Camilla Belle. Though neither Jonas or Belle have confirmed that they were dating, they were often seen together in public. Jonas will continue his world tour, while Belle will film Father of Invention with Kevin Spacey.
