Rap rivals Kanye West and 50 Cent joined some of the biggest names in hip-hop for a supergig in New York City on Wednesday night (22Aug07). The two rappers have been trading insults since they realised their new albums would be released on the same next month (11Sep07). T.I. invited West, 50 Cent, Sean 'Diddy' Combs, Jay-Z, Wyclef Jean, Mobb Depp, Lloyd Banks, Tony Yayo, Swizz Beatz and R+B singer Ciara to join him on stage at Madison Square Garden for the New York leg of his Screamfest tour. After several collaborations between various pairings of the urban stars, West, 50 and Combs teamed up to perform You Can't Tell Me Nothing.
