On November 21, Ed Sheeran made a surprise cameo at 50 Cent’s concert in London.

In a video posted by TMZ, 50 Cent, actual name Curtis Jackson, expressed his delight after Ed fell from the ceiling inside a massive box.

Interestingly, while 50 instructed concertgoers to “put their hands up,” Ed was already performing his 2017 single Shape Of You.

It was at this point that Ed, along with the rapper, took center stage.

Following the performance, 50 took to Instagram to share behind-the-scenes photos from backstage.

Ed and 50 were both wearing black in the images, with the latter wearing faded black jeans and a short-sleeved T-shirt and the former sporting cargo pants.

“My man came through for me tonight, BOOM. LONDON went crazy! It don’t get bigger than this.

Fans commented on the post, with one saying, “50 be having the most unlikely friendships, I love it.”

Meanwhile, Ed published a video that he filmed during the event and subsequently 50 times reposted on his Instagram story, with the caption “teddysphotos.” I had a great time and had the O2 going crazy.”

This is not the first time a vocalist has appeared on 50’s performance; in September, Eminem joined the rapper on stage during the Michigan leg of his tour.

“Detroit make some noise for one of the best friends I’ve ever known 50 Cent! Make some noise for hip-hop’s 50th birthday y’all!”
