The annual star-studded Met Gala went down on Monday night in New York City, and The Weeknd was there to entertain. As the recent collaboration king has been wont to do (you saw the live Lauryn Hill and Bryson Tiller team-ups, yeah? You heard "6 Inch" on Beyoncé's Lemonade, oui?), Abel brought our Mr. Nasir Jones.

Watch above as Nas and The Weeknd rock the Beauty Behind the Madness cut "Tell Your Friends," co-produced (and excellently remixed) by Kanye West. We wouldn't have guessed it, but they've definitely got chemistry, and certainly need to release a studio version of this.

Nas shows up at the 1:30 mark to let us know he's "42, but I fuck 'em like I'm 22" and that he's "been through aunties and mamas, now it's they daughter's turn." Last week, Esco showed up on "The Sickness," a single from the late J-Dilla's next posthumous album, The Diary.

At the end of March, The Weeknd abandoned his primo post as an opener on Rihanna's ANTI World Tour "due to some unforeseen changes with upcoming projects."
