Kanye West, Rod Stewart, and Lily Allen have joined the line-up for the July 1 concert remembering Princess Diana at London's Wembley Stadium, which Princes William and Harry planned to coincide with what would have been their mother's 46th birthday and in memory of the 10th anniversary of her death. The fairly schizophrenic list of performers includes the English National Ballet with songs by Andrew Lloyd Webber "in honor of Diana's love of dancing and theater," as well as Duran Duran, Joss Stone, Pharrell Williams, and Elton John. (Wonder what he'll close with?)
