25 celebrity Man Utd fans you might not know as Harry Styles makes surprise appearance in Luton crowd

The former One Direction heartthrob and Watermelon Sugar singer surprised supporters by taking in the humble surroundings of Kenilworth Road.

There was a surprise megastar in the crowd as Manchester United ran out 2-1 winners at Luton on Sunday. And while not the most vocal of football fans and wearing neutral colours at Kenilworth Road, Harry Styles is in fact a United fan.

Born in Cheshire and involved with the new Co-op Live arena, the former One Direction singer grew up idolising David Beckham. It appears the Luton game was close enough to his London home for him to pop along and take in the action with Rasmus Hojlund firing United to victory. He even met the Sky Sports team including Gary Neville before the game.

He's far from the only celeb United fan as from WWE superstars to Lord of the Rings actors - United certainly have a global fanbase. We've rounded up some of the best below.
