Joe Jonas:"It was weird writing about a boy"

Jonas Brothers recently worked with Demi Lovato on her debut album 'Don't Forget'. They said it was a great experience, but a little strange. Joe laughed, 'It was weird writing a song talking about a boy!' Kevin added, 'We were like, 'So this is what girls go through.'

Also, the guys have just announced that they will be joining Nick's ex girlfriend, Miley Cyrus, to co headline the Concert for Hope benefit on September 14. The concert will help benefit the cancer research and treatment organization City of Hope.
