“The Late Show with David Letterman” has two fun stars appearing Wednesday (April 2) in the form of funnyman Bill Murray and pop superstar Lady Gaga. We never really thought we’d see them meet, let alone take a selfie together, but here it is in all its glory.

We also love how Gaga looks like 10 pounds of crazy in a five-pound bag. She’s a delight.

Gaga then takes Bill, Dave and the entire “Late Show” audience down the street to the Roseland Ballroom, where she performs a couple numbers, including “G.U.Y,” off her latest album, “ARTPOP.”

The singer is actually in the middle of performing a week of shows at the Roseland Ballroom, which will be the historic concert hall’s last concert before it closes its doors for good.

We’ll post video of her performance here as soon as “The Late Show” makes it available.
