Leo DiCaprio celebrated his Oscar win by puffing on a vape pen and sipping a cocktail.

Leo was at Ago restaurant in WeHo to celebrate his win, and he was the center of attention.  

When he left, someone gave him a bottle of booze. And the weirdest thing ... someone ran out after Leo's car with his Oscar, almost as if someone forgot to take it.
