The father of One Direction heartthrob Harry Styles has shared an adorable photo of the superstar as a 4-year-old and it shows him with bright blonde hair and wearing a Mickey Mouse T-shirt.

Writing on his official Twitter page late last night (May 11), Des Styles explained that the picture is of the 'Story Of My Life' sensation at his grandmother's house years ago:

"Just found this photo of H doing some domestic work at Nanny S's in 1997. Aahhh? Seems you liked the photo of H. To answer, yes he was blond - it usual was curly, ringlets and all! No idea why straighter that day?"

Last week, Styles pulled down his trousers during the band's concert at Parque Olímpico in Rio de Janeiro to treat fans to a glimpse of a brand new tattoo, which simply says 'Brasil'. He recently told Capital FM that all One Direction want for their new run of dates is for people to enjoy their concerts:

"[Even] if they're a dad, if they're not necessarily a fan, we want them to still feel like they've seen a show and go away and say, 'Actually they're quite good'. It's important that we make sure the show and the music and everything stays every exciting."
