Two months after announcing Jonas Brothers' disbandment, members Joe Jonas and Nick Jonas recently joined forces to perform at KISS 98.5 FM's Kissmas Bash in Buffalo, New York. However, another member Kevin Jonas was nowhere to be seen at the event for unknown reason.

Despite the oldest brother's absence, Joe and Nick managed to have a lot of fun with the crowd. The two former Disney stars performed Jonas Brothers' hits that included "S.O.S". After the event, they took to Twitter to thank their fans.

"Buffalo you were awesome last night. Thanks," Nick told his followers. Joe added, "We had a great time last night thank you Buffalo for makin our wildest dreams come true. All of them. #boom."

This won't be the first time Joe and Nick reunited for a gig without Kevin. Last month, the duo appeared together to perform at an event in Mexico City. A source close to the brothers later said that Kevin couldn't attend the event because he's "focusing on his business ventures."

Jonas Brothers announced their split back in October. During their visit to "Good Morning America", Joe said, "To just name a few, for us, as a band it was the music, for us, we kind of held on to it for so long. At one point, a year later, we still kind of felt like it was starting to get stale to us."

"There was just individual things that we were just butting heads about whether it was the way to [set up] a music video to even just whatever, even just personal opportunities," he added. "At some point we decided it was best to finish this and support each other in our ventures along the way."
