Happy birthday Mr. Mandela

LEONA LEWIS is set to perform at Nelson Mandela’s 90th birthday concert.

The singer has been added to the star-studded line-up for the former South Africa President’s celebrations in London this summer. The concert will be her biggest show ever and would mark the end of her successful world tour to promote her debut album Spirit. Leona became the first British solo artist to top the US album charts with a debut record, after Spirit sold 205,000 copies in its first week to be number one in The Billboard 200. Her debut US single Bleeding Love topped The Billboard Hot 100 chart, while her mentor Simon Cowell recently said she is the biggest-selling new artist in the world.
