NBC's hit reality series "The Biggest Loser" is about to get a giant special guest. 

 

The network announced today that first lady Michelle Obama will make a special appearance during a two-part "makeover episode" airing on April 3 and April 10. 

 

"The first lady talks to the contestants about how adult behavior impacts kid behavior, congratulates the contestants on being good examples of health and fitness, and visits with each player and their family members," announced the NBC program.

 

According to various outlets, the show will also feature the program's "first-ever White House workout." Woo! 

 

So yea, Michelle Obama is going to great lengths to spread her "Let's Move" initiative — and tapping a top health-centric reality show is just business as usual. 

 

"We share a common goal with the first lady to get people more active and healthy, so both parties felt it was a natural fit to join forces again," the Huffington Post quoted executive producer Todd Lubin as saying.

 

As The Daily Beast recaps in a video montage below, Obama is definitely used to cameos on the small screen — from beating Ellen DeGeneres in a pushup contest to shocking new homeowners on "Extreme Makeover."

 

Have a look at some of her greatest moments so far:
