Rapper Kanye West has taken aim at his pal Jay Z's new Justin Timberlake collaboration Suit & Tie, insisting he is not a fan of the track.

Timberlake ended his six-year hiatus in January (13) with the release of the single, and he teamed up with Jay Z to perform the song at the Grammy Awards earlier this month (Feb13).

The superstars are now headed out on the road together on the Legends of the Summer stadium tour, but West doesn't seem too impressed and on Saturday (23Feb13), he criticised the project during his London concert.

In video footage obtained by Tmz.com, the Stronger hitmaker, who recorded the 2011 album Watch The Throne with Jay Z, tells the crowd, "I got love for Hov (Jay Z), but I ain't f**king with that Suit & Tie."
