Hussle, born Ermias Asghedom in Los Angeles, was shot and killed outside of his Marathon Clothing store on 31 March. His death caused shockwaves in the music world, where stars paid tribute to a man known as much for his generosity towards his community as for his music.
At the O2, Drake asked his audience to "look around and be grateful and happy that we're all here together, alive and well, 'cos life can end at any moment. I just want to say I love you, I'm thank you to be with you tonight.
"London, as long as you'll have me back I'll stand in the middle of this building and give you everything I've f***ing got. Cheers to my brother, rest easy my g."
Drake also projected an image of Hussle's face onto the floor of his stage, telling the crowd: "I want you to make some noise for the people who love you unconditionally, because you never know how short life is."
LA police have identified a suspect in Hussle's killing. Eric Holder, 29, is wanted for homicide, a police statement said.
