Fox is partnering with Howie Mandel on a reality special that’s takes Glee-style musical numbers and puts them into the everyday real world.

Titled Mobbed, the show is a hidden-camera prank series in which Mandel and hundreds of strangers will help special guests plan surprise musical song-and-dance stunts for friends and loved ones.

“It’s so exciting to be a part of this huge musical spectacle never before attempted on this scale,” Mandel says.

Here’s how it works: A big piece of news — marriage proposal, etc. — is delivered to another person with the help of Mandel and his team, which rehearse a giant flash mob musical number throughout the episode. On the day of the event, the prankee is subjected to a huge and unexpected performance, starting with a few dancers and evolving into a giant spectacle.

The project has been in development as a potential series for the past year, and Fox could air more Mobbed if the show delivers a large rating. The show will air after American Idol on Thursday, March 31 at 9 p.m.
