Drake and The Weeknd are both on tour in Europe right now, and after Drake brought his pal Abel out in Germany, the Starboy singer returned the favor by bringing Drizzy on stage in London.

On top of giving the crowd a surprise performance, Drake sung praise for Abel, who worked with him on 2011's Take Care after Drake discovered him while he was working on his debut project House Of Balloons. "You played me 'What You Need.' After that, we met up at the studio and I heard House Of Balloons, which is in my top 5 albums of all time," Drake recalled of his early meeting with Abel.

He closed his speech with the declaration: "OVO and XO forever, it doesn't matter where we are."

Last week, it was discovered that Drake's iTunes bio promised an appearance from The Weeknd on his upcoming project More Life. Noah "40" Shebib, Drake's trusted collaborator, recently suggested he was finishing More Life, which is expected to arrive very soon after it did not see release at the end of February as Drake last hinted.
