Jay-Z joins Linkin Park on stage for encore

'Big Pimpin' hitmaker Shawn 'Jay-Z' Carter stunned thousands of fans at a Linkin Park concert recently when he joined the rockers onstage for a surprise encore.

The band had just announced: "Good night, New York!" to a sold-out crowd at Madison Square Garden last Thursday when the hip-hop star stormed the stage to jam with the band.
