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.

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.

Justin was also guest on The Tonight Show with Jimmy Fallon and took part in an excellent 'History of Rap 6' sketch.

The sixth instalment of the sketch saw Justin and Jimmy perform a 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'.
