In a sentence we never expected to write, has thrashed Harry Styles in a dodgeball match.
Before you ask, the match was to honour James Corden's Late Late Show filming in London and featured two very A-list teams - one of Brits and the other, Americans.
Leading the British side was Corden who called on friends Styles, Benedict Cumberbatch, Game of Thrones' John Bradley and Reggie Watts - a musician on his show who is also American, actually.
Who better to head up the US side than a former First Lady? Obama enlisted a formidable team of women including Kate Hudson, , Melissa McCarthy, and to take on the British men.
'You would not believe how easy it was to get people to do this,' Obama joked in a promotional video. 'All I had to do was tell people: "You're going to throw a ball at James Corden."'
'When Michelle Obama calls and asks you to do anything, you just say yes,' Kunis told the camera, instantly clarifying why all these women had rallied together to play a kind of strange sport we once had a PE lesson on.
In the clip, Obama is seen giving her team a pep talk while McCarthy, understandably, gets tearful.
'When we go low... we also go low,' she says.
Obama, who spearheaded a get fit initiative to combat childhood obesity while in office, demonstrated her commitment to sport by lobbing a ball at Styles, which then saw him crumbling to the ground and eliminated from the game.
Elsewhere, Cumberbatch's face lit up with immediate horror after realising he'd pelted a former First Lady in the stomach with a ball.
Previously, Obama joined forces with Corden to take part in his Carpool Karaoke series with none other than Missy Elliot.
Note to late night hosts: more Michelle Obama in comedic skits please.
