"Are you ready to take a class with the harshest, toughest group of choreographers in all of Los Angeles?" James Corden asks Jenna Dewan Tatum, his guest on the Late Late Show last night.
Considering she's a professional dancer, Dewan Tatum wasn't worried. Come on, have you seen her moves on Lip Sync Battle? She's got some serious skills.
But she was definitely in for a one-of-a-kind dance experience. The choreography class would be led by a group of toddlers making up the moves as they go.
Set to Sia's song "Alive," they did leg kicks, floor spins, some running, and lots of jumping around.
See what else the kids came up with in the video above.
