Entertainment Weekly reports that as a part of her Joining Forces program to support the US military troops and their families, First Lady Michelle Obama will make an appearance on the Nickelodeon television program iCarly.  Miranda Cosgrove (“School of Rock”) plays a girl whose father is a U.S. Air Force officer stationed on a submarine.

Carly’s friends set up a webcast so Carly (Miranda Cosgrove) can communicate with him at a military base. With a few Secret Service agents in tow (including one played by… Saturday Night Live’s Taran Killam!), Mrs. Obama surprises Carly and Co. to commend them for supporting military families (as part ofthe First Lady’s Joining Forces initiative). The kids invite her to appear on iCarly, and not only does she oblige, she even engages in some random dancing.

The Entertainment Weekly site has a clip of Mrs. Obama’s appearance on the show, which will be broadcast January 16 at 8/7 central.
