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 (21Feb08) when the hip-hop star stormed the stage to jam with the band. Jay-Z and Linkin Park proceeded to play two songs together, including their Grammy-winning collaboration Numb/Encore and a remix of the rockers' Faint with the rapper's Jigga What, Jigga Who.
