Eminem and Jay-Z Tape 'Letterman'

Eminem evaded photographers outside the Ed Sullivan Theater in New York City on Monday (June 21), where he taped “The Late Show with David Letterman.” Jay-Z was more camera friendly, throwing up the diamond while entering the studio.

Both rappers were there to perform on the rooftop and promote their joint concerts at Detroit’s Comerica Park and New York’s Yankee Stadium in September. The episode will air on Friday.

Diddy also stopped by to toast his hip-hop peers with a glass of wine in hand. “I’m just here as a fan,” he told Fox 5 New York.
