Even after Norm Kelly told Meek Mill he wasn't welcome in Toronto, the Philadelphia rapper defied the Ward 40 councillor's wishes and performed during the Nicki Minaj show at the Molson Canadian Amphitheatre last night.

Concertgoers weren't too pleased with his appearance and reportedly booed while he was on stage. That's because Mill is feuding with Drake, a Canadian hero, at least according to Kelly.

It all started after Drake appeared on Mill's song "R.I.C.O.," off the album Dreams Worth More Than Money. In July, Mill accused Drizzy of using a ghostwriter for his verse. The 6ix rapper fired back with a diss track called "Charged Up."

Overnight, he dropped yet another one. "When I look back I might be mad I gave this attention, but it's weighing heavy on my conscience," raps Drake on "Back to Back."

Along with his snappy one-liners, he went one step further and used an image from the 1993 World Series for the track's art. To jog your memory, the Blue Jays beat the Philadelphia Phillies that year.

"Back to Back" features Drake freestyling over a simple beat as he continually throws out zingers like, "This for y'all that think that I don't write enough. They just mad 'cause I got a Midas touch." Meek Mill has yet to respond.

What do you think of the of this ongoing feud? Let us know in the comments.
