After President Barack Obama read mean tweets on "Jimmy Kimmel Live!", now Michelle Obama gets groovy on "The Ellen DeGeneres Show". The First Lady dances to Bruno Mars' "Uptown Funk" with "So You Think You Can Dance" troupe.

Mrs. Obama tells Ellen DeGeneres that the dancers will perform a choreographed routine on the White House lawn at this year's Easter Egg Roll to celebrate the fifth anniversary of her Let's Move initiative. "There is some hip thrusting," so she teases.

"We're asking folks all across the country to #GimmeFive ways their leading a healthy life," the First Lady also says. "Beyonce gave me five, and Ryan Seacrest and Nick Jonas and even the astronauts on the space shuttle, the International Space Shuttle, got involved."

Mrs. Obama then challenges DeGeneres to show her moves. "I hear you have sort of been practicing," she says, to which the host jokes, "I've been practicing somewhat. I'm very busy, very, very busy and I'm not really good at choreography I'm more of a free style. Kind of street dancer."

A sneak peek to the interview is released ahead of the Monday, March 16 airing.
