Michelle Obama among Jimmy Fallon's first guests as he takes over 'Tonight Show

Jimmy Fallon is taking over as host of NBC's "Tonight Show" this week and he's nabbed some high-wattage guests including comedian Jerry Seinfeld, singer Lady Gaga and first lady Michelle Obama.

Michelle Obama will make her appearance Feb. 20, according to a show schedule sent out by NBC. The last time Obama and Fallon were together was nearly a year ago to the day. The two did "the evolution of mom dancing" together, a series of awkward dance moves meant to promote Obama's "Let's Move" exercise campaign.
