Her $4 million taxpayer-funded vacation seen nodding in approval.

Via Entertainment Weekly:

The gang at iCarly have gotten into some high-level high jinks over the years, but this time it’s going all the way up to the White House. Yes, the First Lady herself, Michelle Obama, will guest-star on an episode of the hit Nickelodeon sitcom airing Jan. 16 at 8 p.m.

What exactly brings President Obama’s better half to Seattle? When Carly’s dad, an Air Force colonel, can’t make it home for his birthday celebration, 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 of the 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. Below, you can sneak a peak at a clip featuring the First Lady, a.k.a. “Your Excellency.”
