(Radio.com) As celebrities' numerous selfies and social media posts from the Met Gala make their way online, a new video gives a behind-the-scenes look at a special performance from The Weeknd and Nas.

The Weeknd performed a small set at the event Monday night (May 2). When he decided to "slow things down," he chose his Kanye West-produced track "Tell Your Friends" from his 2015 album Beauty Behind the Madness. New York rapper Nas came out halfway through to help.

The slow and sultry song gets a bit of pep from Nas' verse. He raps about everything from his bedroom swagger to his cash flow still going strong. He may be 42, he says, but he can still get down like he's 22. No doubt.

Seeing as how Kanye was in attendance, sporting blue eyes and all, we wonder what he thought of the performance. Watch The Weeknd and Nas do their thing here.
