The Jonas Brothers are poised to knock the Kardashians off their tarnished reality TV throne. The even more famous family — Kevin, Joe and Nick Jonas — have a development deal with E! and are filming a “family reality show,” sources tell us. The JoBros appeared in a Disney Channel reality series, “The Jonas Brothers: Living the Dream,” which ran until 2010. We’re told the new E! show will be based in New York. Kevin would be filmed with his wife, Danielle Deleasa, while Nick is appearing in Broadway’s “How To Succeed in Business Without Really Trying.” And Joe last month revealed he has found an apartment in town and will be spending more time here. Reps for the Jonas Brothers didn’t get back to us.
