The Weeknd surprised an audience of people by bringing out the legendary , Lana Del Rey, to perform onstage with him.

On the second night of his Madness tour at The Forum in Inglewood California, the Weeknd snuck the songstress onstage to perform his song “Prisoner” with her. She belted out the song in that quivering alto that has become so irrevocably hers. The morose duet is a show worth watching.Various fans have uploaded grainy footage of that night that can be found on Youtube. Here is a link to a video of the performance, check it out while you can.

All of this fun is in light of the madness The Weeknd is currently battling. According to Pop Crush, Drake’s old pal is being sued for stealing music to use as a sample for his song “The Hills.” The site writes:

“Cutting Edge Music Limited alleges that the “Can’t Feel My Face” singer illegally sampled music from the 2013 movie The Machine to use for his chart-topping hit “The Hills.” Court papers filed yesterday (December 9) indicate the case’s key evidence lies in an alleged direct message the Weeknd reportedly sent to Tom Rayboud — who created the film’s score — saying, “I sampled your music might make it 2 the weeknd next album. Huge fan of what u did 4 the machine movie!”

The popstar doesn’t seem too worried. He’s touring, being nominated for Grammy after Grammy, and gets to perform with gorgeous talents like Del Rey. It’s anyone’s guess to see where it goes.
