WATCH: Justin Timberlake & Jimmy Fallon dance to Beyoncé's 'Single Ladies' at US Open

Justin does it again!

Published 10th Sep 2015

Proving yet again that he’s the coolest man in pop music, Justin Timberlake broke out into an impromptu dance to Beyoncé’s ‘Single Ladies’ at the US Open with a little help from comedian Jimmy Fallon!

The good friends were watching the quarterfinal match between Roger Federer and Richard Gasquet at New York’s USTA Billie Jean King National Tennis Center when the camera panned to them during the interval.

With ‘Single Ladies (Put a Ring on It)’ blaring through the speakers, Justin was coaxed into re-enacting his legendary dance to the song on Saturday Night Live in 2009. Unsurprisingly, the former N*Sync star gamely got to his feed.

With cameras capturing the hilarious moment, both Justin and chat show host Jimmy busted some Queen Bey moves to rapturous applaud from the 23,000 capacity crowd.

Truly incredible scenes!

Later on last night, Justin was a guest on The Tonight Show with Jimmy Fallon where they took part in the History of Rap 6 sketch.

The sixth instalment of the sketch saw Justin and Jimmy perform a sprawling medley of hip-hop classics in six minutes including Snow’s ‘Informer’, Public Enemy’s ‘Fight The Power’, Drake’s ‘Know Yourself’, Jay Z & Kanye West's 'Otis' and Beastie Boys' 'Fight For Your Right'.
