Fifth Harmony, Icona Pop, The Wanted, Midnight Red, Cash Cash and Tegan and Sara turned up the show at KISS 98.5 FM's Kissmas Bash at First Niagara Center in Buffalo, New York last night. Guess who else performed? The Jonas Brothers! Well, just Joe and Nick.

After cancelling their fall tour and announcing the band's official and final split, fans were left horrified after their favorite bros called it quits. Brothers cannot "break up" but whatever "deep rif within the band" happened made it as serious as to devastate millions of followers. Today we understand the band's decision much more as Joe Jonas put out his famous open letter and Kevin Jonas is becoming a father soon. The brothers just grew apart and wanted to break the squeaky-clean image that they had created. As Joe and Nick seem to be able to still work together, it looks like the main problem here might have been big bro, Kevin.

Nick and Joe performed a number of JoBros hits including their "S.O.S" single. Fans were super excited to see at least two out of the three brothers come together at the Kissmas Bash last night. "Buffalo you were awesome last night. Thanks" tweeted Nick to fans after the show. Joe also added "We had a great time last night thank you Buffalo for makin our wildest dreams come true. All of them. #boom". Nick and Joe will continue their two-man tour in Chicago tonight for B96 Pepsi Jingle Bash alongside Avicci, Ariana Grande, Austin Mahone, Armin Van Buuren, Jason Derulo, The Wanted, EMBLEM3, Midnight Red and Pitbull. By the looks of it, it's going to just be Nick and Joe for a while as there are no signs of Kevin anywhere.

Even though a source told E! News at the time of the break up that "there were no personal issues" between the siblings we have to believe otherwise at the constant absence of Kevin. It looks like Kevin just grew into adulthood and would rather be with his wife waiting for his new child. Maybe he will even start a solo career where he can sing songs more compatible with his own life.
