In Tuesday’s part 1, the Loser-ettes will get made over to make a trip to the White House after watching a video invite from the First Lady.

When they get there, their loved ones are waiting to surprise them.

Oh — Spoiler Alert.

The Loser-ettes don’t get to see the First Lady in person until part 2, the following Tuesday, when she appears to welcome them to 1600 Pennsylvania Ave., and talks to them about how adult behavior impacts kid behavior — part of her Let’s Move! initiative to solve the problem of childhood obesity. After that, the “Loser” trainers lead the First Lady, Loser-ettes, and their loved ones through that “The Biggest Loser” first ever White House workout.

Wednesday’s First Lady Booking comes on the heels of Nickelodeon’s announcement she would stop by its Kids Choice Awards, taped live in Los Angeles on Saturday, to honor country pop singer Taylor Swift with the Big Help Award.

The prize — given to Michelle Obama herself in 2010 — honors people who try to make the world a better place.
