The actor, who portrayed American showman P.T. Barnum in the movie musical, will perform "The Greatest Show", which will be directed by Michael Gracey, the man behind the film.
Hugh confirmed his Brit Awards appearance in a video he posted on his Instagram page, in which he pledges to keep the big news to himself, whispering, "Don't tell anybody, keep it to yourself, I know it's amazing but keep it to yourself...".
He then enters a studio and announces to his dancers, "We're opening the Brits. Oh no! I didn't tell you that, I didn't tell you anything... we're just going to rehearse. It doesn't matter what we're rehearsing for. Why don't we just work on 'The Greatest Show' for no reason? Don't tell anyone, I shouldn't have told you."
Brits chairman Jason lley has also confirmed the big news in a statement, which reads: "We are delighted to welcome the Golden Globe and Tony Award-winning superstar Hugh Jackman to the Brits stage this month with a performance that is set to be nothing short of spectacular.
