All the single ladies at the U.S. Open, put your hands up. Jimmy Fallon and Justin Timberlake, you're welcome to join in too.
The Tonight Show host and multifaceted entertainer (presumably) heard Beyonce's "Single Ladies" sound through Arthur Ashe Stadium on Wednesday and, in good Fallon-Timberlake fashion, immediately broke out in the dance made famous by the music video.
And they nailed it.
Timberlake did look a little more well-versed, but, of course, he's had a bit of help from Queen B herself.
