And the brash-talking British banger is already having some fun at his opponent's expense.
Taking to Instagram, Bisping posted a backstage encounter with St-Pierre, in which the former welterweight king simply tried to board an elevator and get along on his merry way.
Bisping, however, doesn't let anything happen quite that easily. If you stand in his path, you're subject to verbal jabs aplenty, and St-Pierre received a solid fistful.
"Sweet dreams. Train hard. Take steroids -- don't get caught though! Don't get caught!" Bisping is heard barking toward the Canadian superstar.

It's all in good fun, of course. Bisping is arguably the best trash-talker in the sport, and there's no doubt going to plenty more where this came from ahead of their much-anticipated showdown.
