Margot Robbie -- Hot Chick from 'Wolf of Wall St.' ... PDA at NY Rangers Game

So, the hot chick from "The Wolf of Wall Street" has a boyfriend ... and she proved it by getting all touchy-feely with the guy at the Rangers game Wednesday night.

Her name's Margot Robbie -- she's the chick who banged ... and then had a kid with ... Leo's character in "Wolf."

But at the game last night, the 24-year-old was all snuggled up with Tom Ackerly -- an aspiring assistant director -- as the Rangers beat the Philadelphia Flyers 2-0.

The pair have reportedly been dating since June.

Danny DeVito and Michael J. Fox were also spotted in the stands. Check out the pics in the gallery.
