Despite buzz to the contrary – and Nick Jonas's ongoing solo project – the Jonas Brothers are not splitting up, Joe tells PEOPLE. "We are happy being a band, and it's what we've always wanted to do," he says. "We are not breaking up. There's no reason for us to do that."
But that doesn't mean the band of brothers aren't pursuing other interests as well. Joe spent his day in Washington at a fun run for the Special Olympics, met with Speaker of the House Nancy Pelosi, and lobbied for new legislation for the event.
"The athletes are so incredible – the way they carry themselves and their joy for life," says the musician. "That's something I aspire to be like one day."
In addition to his work with the Special Olympics, Joe has helped build orphanages in Mexico and Haiti, while his brother Nick lobbies for diabetes research and Kevin counts volunteerism as his cause.
Their charitable efforts – the band founded the Change for the Children Foundation – haven't gone unnoticed: The Jonas Brothers and their management team will be honored by the TJ Martell Foundation at Roseland Ballroom in New York City April 18, where they'll also perform.
"It's really cool," says Joe. "I can't believe it. I think I'm just getting started, so to be honored already seems too early."
And in between all the band's engagements, Joe happily reports that he still finds time to write new music. In fact, he says, "I can't stop."
