Jay Z invited Chris Martin of Coldplay to join him on stage during his second night at London's O2 arena this week to perform a track from one of his early albums. See a video of the performance below.
The superstars (and good friends) performed 'Aint No Love (In The Heart Of The City)' together, with fans taking to Twitter after the show to speak of their amazement at seeing the live collaboration. 'Ain't No Love (In The Heart Of The City)' originally appeared on Jay Z's 2001 album, The Blueprint, sampling a track of the same name by soul singer Bobby Bland.
"So Jay Z was unbelievable last night and he had Chris Martin as special guest. Timbaland was on the decks," wrote Will Newman after the huge gig.
"Still can't believe I saw Jay Z last night and that he brought out Chris Martin," tweeted Jess Maynard.
"Most amazing performance I have ever seen! Jay-z, timberland and an appearance from Chris Martin!!!" said Lauren Stoner.
