I seriously doubt LeBron was really taking vodka shots in his latest appearance on The Ellen show. He is a pretty good actor, just ask a lot of defenders in the league and anybody who saw the hilarious 'Trainwreck."
The reason why he was taking "vodka shots" is because every time Ellen made a shot in the wastebasket challenge, he had to take a shot.
I'm also sure LeBron would say this challenge was tougher than playing Faceketball with Jimmy Fallon.
But not as tough as playing Ricardo the Busboy in the Pop-a-shot challenge on Jimmy Kimmel.
