Rap superstar Jay-Z is to join his rocker pals Coldplay to perform at the closing ceremony of the Paralympic Games in London later this month (Sep12).

The British band has been lined up to help close the event on Sunday (09Sep12) and the rockers are reportedly planning to join Rihanna onstage for a rendition of their collaboration Princess Of China.

Now a new report suggests 99 Problems hitmaker Jay-Z - who is a close friend of Coldplay frontman Chris Martin - has agreed to perform a set at the spectacular event, and will even join Martin for a duet.

A source tells British newspaper the Daily Star, "Jay-Z and Chris Martin are close friends so he helped to get the rapper on board. They are putting together a spectacular set list - one likely to include a duet."
