LeBron James, Draymond Green, Kevin Hart and more hit up a secret VIP party for Drake last night in Toronto ... complete with a celebrity DJ and DAVID BLAINE doing magic ... TMZ Sports has learned.
It all went down at Frings -- owned by one of Drake's good friends -- and we're told the party was very strictly invitation only.
We're told the party was to honor Drake -- who's getting the key to the city this week ... as part of the kickoff to NBA All-Star weekend.
