WATCH: Michelle Obama dances with Will Ferrell and Jimmy Fallon for hilarious sketch
The FLOTUS is one of many high profile guests the new host has had since taking over the Tonight Show reins earlier in the week from Jay Leno.
And while she may have been on a high-rated comedy show, Mrs Obama was there to once again highlight her message of healthy eating and exercise.
The segment, 'EW!' sees Fallon and special guest Will Ferrell posing as teenage girls who respond, 'Eww' to absolutely everything.
When asked if she was watching the Winter Olympics, she said: "Absolutely, I love seeing the best athletes in the world competing against each other. I enjoy them all but one of my favourites is figure skating."
She then takes part in a three-person 'high five hug' with the two legendary comedians.
Michelle also revealed her favourite exercises before taking part in a dance-off with the two.
"Exercise is not' EW', you just have to find an activity that's right for you. For example, I like to dance, play tennis - even do some push ups," she explained.
he then proceeded to share kale chips as a healthy snacking alternative.
