NEW YORK - Joe Jonas is tired of hearing about how he's a bad boyfriend - and now he's trying to defend himself. The 19-year-old - part of dreamy teen band the Jonas Brothers with his two siblings - has gotten an avalanche of negative publicity after former girlfriend and fellow multiplatinum singer Taylor Swift dished about their recent breakup, which she says came in a 27-second phone call. She also was quoted as saying that he dumped her after meeting actress Camilla Belle.

The revelations have been hot topics on the blogs and have muddied his reputation as a clean-cut, upstanding heartthrob.

So, in a posting on the MySpace.com celebrity blog page Thursday, the singer sought to give his side of the split, though he didn't mention the 18-year-old country star by name. (It had also been posted to the Jonas Brothers' own MySpace page but had been removed by Friday afternoon.)

"I never cheated on a girlfriend. It might make someone feel better to assume or imply I have been unfaithful but it is simply not true," he said. "Maybe there were reasons for a breakup. Maybe the heart moved on. Perhaps feelings changed. I am truly saddened that anything would potentially cause you to think less of me."
