Drake held the OVO (October’s Very Own) Fest in his hometown Toronto over the weekend with guests like Young Jeezy, Rick Ross, Fabolous, and Bun B. But he saved the best for last.

After Drake rapped his opening verse from Forever, out came Eminem, who he called the greatest of all time.

And then Jay-Z came out to do a verse from Run This Town. Drake has stated before that Jay-Z is the most influential MC in his life.

Both superstars are getting ready for a couple of concerts they’re doing together in Detroit and New York in September.
