Ariana Grande Is ‘Still Shaking’ From Her Dance Rehearsal With Madonna

The ‘two clowns’ shared a sweet backstage moment

Mariah Carey may insist she doesn't know who Ariana Grande is, but Madonna surely does. Earlier this month, Ari shook what her mama gave her at a benefit concert hosted by the "Material Girl" herself.

Leonardo DiCaprio, Paris Hilton, Chris Rock, and more celebs showed up for the night's auction, which raised a whopping $7 million for Raising Malawi, a nonprofit organization co-founded by Madonna. The foundation supports underprivileged children growing up in Malawi, Africa.

On Monday (December 19), Madonna revealed one of the night's biggest highlights that the guests didn't see: her backstage rehearsal with Ari. They both performed at the party, so they snuck in a few shimmies together before the curtain went up.

"How long do we shake it for?" Ari asks mid-routine. "Till I say stop!" Madonna answers.

Ariana reposted the same video a few hours later, adding that she was "still shaking two weeks later." Never say Ari doesn't commit.
