Kanye West, Rod Stewart, Lily Allen and Status Quo are among the eight artists added to the line-up for a summer concert at London's new Wembley Stadium to commemorate the 10th anniversary of Princess Diana's death.

Natasha Bedingfield, the Feeling, James Morrison and Orson are the other acts confirmed today for the Concert for Diana, to be held July 1.

They join previously announced performers, including Elton John, Duran Duran, Bryan Ferry, Joss Stone and Pharrell Williams. And in recognition of the late Princess' interest in the arts, the event will feature the English National Ballet, while composer and impresario Andrew Lloyd Webber will oversee a medley of songs from some of his leading theatrical shows.

The concert is to be staged on what would have been the Princess' 46th birthday. "We wanted to have this big concert...full of energy, full of the sort of fun and happiness which I know she would have wanted," said her son, Prince William, in a statement. "And on her birthday as well, it's got to be the best birthday present she ever had." The event is the brainchild of William and his brother Harry.

A spokesperson, meanwhile, has downplayed speculation of a rift between the Diana concert's team, and organizers of the Live Earth concert on July 7, noting, "it's all peace and love between the two events, so much so that they are sharing many of the facilities/staging." Live Nation in producer of both concerts.

An additional 10,000 tickets for the July 1 concert will go on general sale tomorrow morning via Ticketmaster and via the event's official Web site. Tickets, at £45 ($90) each, went on sale Dec. 13. Wembley's capacity rises above 60,000 for concerts.
