Nick Jonas is going solo!

The Jonas Bro, 17, has started his own band, his mom confirms to Parade.com.

"Nick is working on a solo act -- it's called Nick Jonas and The Administration. Shhh!" Says his mother, Denise Jonas. "He's at the photo shoot for the album cover right now."

Denise also reveals that her son Kevin Jonas, 21, has set a wedding date with fiancée Danielle Deleasa.

"Kevin and his fiancée Danielle have set their wedding date -- but it's completely private," Denise teases.

She's a fan of Deleasa, to whom her son became engaged to in July.

"Danielle, bless her heart, is from a great little Italian family. She is everything I ever prayed for and hoped for Kevin," she said.
