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.
