Nelly Furtado also signs up for Wembley bash
P Diddy has joined the line up for the Princess Diana memorial concert.
Nelly Furtado, Will Young, Tom Jones and Supertramp singer Roger Hodgson have also been added.
The late princess was said to have been a big fan of Supertramp, who were a massive-selling act in the late 70s.
As previously reported Pharrell Williams, Lily Allen, Kanye West, Take That, Elton John, Duran Duran, Joss Stone and Bryan Ferry are set to play the gig, which takes place at the new Wembley Stadium in London on July 1.
Tickets for the gig sold out within minutes, reports The Times.
