Joe Jonas made the announcement this weekend to his Twitter followers, writing that he would be joining Spears Aug. 5 at the Izod Center in East Rutherford.
Jonas, the middle of the Jonas Brothers lineup, joins a growing roster of supporting artists in the Femme Fatale lineup, which also includes Nicki Minaj and DJ Pauly D, MTV said.
Jonas has been busy wrapping up a long-awaited solo album, which MTV said would be released in October instead of early September. He was recently seen in Paris shooting a video for "Just in Love with You," one of the singles from the project.
