-- Who run the world? Beyoncé!
And she proved as much when she stormed the stage during the season two premiere of "Lip Sync Battle" Thursday.
But it was his rendition of Queen Bey's "Run the World (Girls)" on the Spike TV series that got the crowd most excited.
Performing in full costume, complete with a blond wig, crop top and thigh-high boots, Tatum, 35, began the performance by jumping off a fake horse. After slaying Beyoncé's moves to perfection, Tatum stunned the crowed when Beyoncé herself strutted onstage with four dancers of her own.
The two finished the performance together, hugging it out and playing in each other's hair.
Talk about girl power!
Dewan Tatum, 35, even fell to the floor in shock after the epic performance.
Still, she didn't just sit on the sidelines during "Lip Syn Battle." The actress also impressed the crowd with her own take on Ginuwine's "Pony." She even treated her hubby of six years to a lap dance, a nod to his memorable role in the 2012 film "Magic Mike."
