Rap superstar JAY-Z stunned his pal Chris Martin on Friday (18Sep09) when he joined the rocker and his band Coldplay onstage during their London concert and began wrestling him to the ground.
The Run This Town hitmaker, real name Shawn Carter, has been entertaining fans as the support act on Coldplay's current U.K. tour - but he had a surprise in store for Martin when the Violet Hill stars performed at Wembley Stadium.
According to reports, Jay-Z appeared on stage as Martin was playing a song on the piano and embraced him in a bear hug before playfully tackling him to the floor.
The friends rolled around on stage before Martin managed to climb to his feet and resume his set.
A source tells OK.co.uk, "It was a strange moment, Everyone went wild when Jay-Z joined the boys on stage but seeing him grab Chris away from the piano and on to the floor was a bit weird to say the least."
But that wasn't the audience's only surprise - Star Trek actor Simon Pegg also joined Coldplay at their London gig and showed off his skills on the harmonica during the band's rendition of Trouble.
Jay-Z and Martin have been close friends since collaborating in the studio together in 2006 and the pair is regularly spotted out on dinner dates with their respective wives Beyonce and Gwyneth Paltrow.
