OVOXO unites onstage once again.

Joining The Weeknd’s “Legend of the Fall Tour” at the O2 Arena in London on Wednesday (March 8), Drake surprised fans with some serious praise for his fellow Canadian.

“We met up at the studio and I heard [2011’s] House of Balloons, which is in my top five albums of all time,” Drizzy told the British crowd. “Since then, my brother has gone on to become the biggest…OVOXO forever. It doesn’t matter where we are. It’s all love. For real.”

The Weeknd returned the love, embracing Aubrey Graham, and calling him “the biggest artist in the world.”

Bryson Tiller, who is opening for The Weeknd, celebrated this unity on Instagram. Sharing a photo of the duo, he captioned it: “two legends!!”

Fans may recall that Drake was actually returning The Weeknd’s favor. Last month, it was the XO boss who popped up during a “Boy Meets World Tour” stop in Germany.

But the unity has gone beyond the stage. Recently, Drizzy appeared in Abel’s star-studded “Reminder” video, which also featured A$AP Rocky, French Montana, YG, and Pen Griffey.

The duo famously worked together on Drake’s Take Care and they may be coming back with a new collaboration soon. Drizzy’s Apple Music bio notes that the forthcoming More Life project will feature “collaborations with Nineteen85, The Weeknd, and Maneesh Bidaye as well as Boi-1da.”

Plus, The Weeknd has left the door open for a joint project. “[Drake] came in as my big bro and showed the world what I could do,” he told Beats 1 in November. “From then on, he’s always been supporting me and I’ve always been supporting him. Behind the scenes, we’re still very close but it’s cool that the world can see us doing our own thing. OVOXO will always be there.”

As for the possible joint project? “Maybe,” he added. “Why not?”
