Lmao! Drake Mocking Meek Mill Rocking a 'Free Meekmill' Tee

Drake was sporting a FREE MEEK MILL t-shirt in Toronto, reportedly just hours before getting on stage for his OVO Fest -- and the Internet is losing its collective mind.

Photos and vids of Drizzy taking the fashion shot during what looks like a rehearsal .... have everyone wondering if he'll take the next step -- wear it on stage when he headlines tonight.

Drake wore the same shirt last summer to show love to Meek, who was locked up at the time.

Meek mill is definitely going to have a bad day...
