Kanye West Plays Secret Gig

Hip-hop star Kanye West entertained 500 fans at a secret London gig on Monday.

The Touch The Sky star paid tribute to Shawn 'Jay-Z' Carter by dedicating his new song Big Brother to the rap mogul at the concert in Westminster Central Hall.

During his gig, West told fans he was looking forward to his forthcoming chart battle with 50 Cent - whose new disc Curtis hits stores the same day as West's Graduation.

West said, "It's a good thing that 50 Cent and me are coming out on the same dates. I think we both up'd our games because of it."

"Hip hop is so sparse, people are just dropping albums aimlessly."
