Joe Jonas has hit back at Taylor Swift following her claims that he cheated on her with current girlfriend Camille Belle.

The Jonas Brother has posted a lengthy blog on the band's MySpace page urging fans to read the "truth" about their bitter breakup.

Joe's country singer ex recently had a thinly-veiled dig at Joe on her own page after he allegedly dumped her over the phone.

She later sniped that their split was because of Camille.

Joe's blog in full:

To Our Fans from Joe:

This blog is not an attack of anyone. Anytime you are in a relationship for any length of time there are going to be issues. Sometimes they resolve. Other times they lead to a change of heart. This was the case recently.

Several things I will state with all my heart…

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. 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.

For those who have expressed concern over the "27 second" phone call. I called to discuss feelings with the other person. Those feelings were obviously not well received. I did not end the conversation. Someone else did. Phone calls can only last as long as the person on the other end of the line is willing to talk. A phone call can be pretty short when someone else ends the call. The only difference in this conversation was that I shared something the other person did not want to hear.

There were later attempts at communication that had no response.

I wish the best for the other person but could not sit back any longer and leave our fans with a wrong impression of the truth.

Hope this helps enlighten a little.

We love you and miss you

Joe, Kevin and Nick"
