Jennifer Lawrence's 'X-Men: Days of Future Past' boyfriend Nicholas Hoult downs dangerous 'Flaming Shot' of alcohol [WATCH VIDEO]

Jennifer Lawrence may star in "The Hunger Games: Catching Fire," but it's her boyfriend Nicholas Hoult who almost burst into flames in a recently-leaked viral video!

Hoult was hanging-out with some fellow ""X-Men: Days of Future Past" co-stars at a popular Montreal bar sometime last year. Apparently under some "liquid courage," someone must have dared the actor to take a "flaming shot" of alcohol.

In the exclusive RadarOnline clip, James McAvoy "sparks a lighter" into the 24-year-old British heartthrob's mouth after he downs a shot of sambuca (according to eyewitness sources).

When Hoult's mouth ignites in flames, McAvoy can be heard yelling - "It looked like it went up your nose!"

This isn't some prank that just anyone should try - flaming shots are known to be very dangerous, and several individuals get severely burned by such attempts.

But anyway, check out the video below.

Drinking - just one thing Hoult and J-Law apparently have in common!

The "X-Men" sweethearts have been dating on-and-off for three years now.
