Washington, Oct 28 American boy band Jonas Brothers have in a letter to fans denied rumours that they are breaking up, stating that they would continue making music together.

The rumours had started after word spread that Nick Jonas, 17, had formed a band called Nick Jonas and the Administration and they intensified after it was revealed Kevin, 21, is getting married.

"We plan to make music together for as long as we can," People magazine quoted the brothers as saying in a letter to fans.

"We've said from the beginning of our career as the Jonas Brothers that anything we do outside of the group is a side project because you can't break up brothers," Nick wrote of Nick Jonas and the Administration, which is releasing an album next year.

"My brothers are my biggest supporters, and were on the phone with me everyday while I was in the studio asking how it was going, and telling me they couldn't wait to hear the record," he stated.

"We are so proud of our brother Nick. We know that we will be doing music together for the rest of our lives. But we are thrilled for you to hear these songs that were on his heart," Joe and Kevin wrote in a joint message.

"A three-chord strand is not easily broken, and one thing's for sure... this three chord strand is stronger now than it's ever been. You are truly the best fans in the world, and we love you with all our hearts," they added. (ANI)
