Looks like the after party for Wayne’s I Am Still Music stop in Canada last night didn’t end so well, as the rapper and all club-goers were subjected to nasty pepper spray by some jerky patron in the club!! SMH!! Details of the incident after the jump.

It all went down last night at a club in Montreal called La Mouche — where Weezy was hosting the afterparty for his show.

We’re told some jackass snuck into the back room and unleashed the chemical into the ventilation system — and everyone had to be evacuated, including Weezy.

So far, it’s unclear if police are investigating — but a rep for Lil Wayne says the rapper is “okay and gearing for his next stop in Toronto.”
