Rihanna joins Paul McCartney on stage in Indio
Rihanna joined Paul McCartney during his second 'Desert Trip' gig last night. The duo performed their joint hit 'FourFiveSeconds.' Kanye West, who is featured and co-wrote the song, was not there for the performance. "We've finally found someone under the age of 50", said the Beatles legend, possibly referring to the very few who knew the song. Ha!
