Eminem became the first rapper to headline Wembley Stadium, and he did so with a flourish, bringing out Dr. Dre as a surprise guest. After paying homage to Biggie and Tupac by performing "Dead Wrong," he introduced Dre, who came out to "Still D.R.E." After taking fans back even further by performing "Nuthin But A G Thang," the two rocked their collaboration "Forgot About Dre."

Despite some difficulties with Wembley's sound system, Em's first show seemed to be as great as expected. The question is: Who will he bring out for tonight's encore performance?
