South Korean football star is Underwear's newest brand ambassador.

The 30-year-old is set to model for the iconic label's 2022 fall campaign, including the “Embossed Icon” and “Modern Cotton” collections.

The Tottenham Hotspur forward became the first Asian player to win the Premier League's Golden Boot last season, tying Mohamed Salah with 23 .

“As a longtime fan of Calvin Klein Underwear, I'm very excited to be with them as a brand ambassador in Korea,” Son Heung Min told the press about his new endorsement deal.

“Calvin Klein Underwear has been with me in my daily life, so I think my partnership with the brand is very natural. Like many people around the world, I have been inspired by the brand's iconic campaigns, so I'm really looking forward to being the face of this one.”

Son, who also inked a clothing deal with British house Burberry earlier this year, joins as one of the Premier League's most fashionable footballers.

Grealish shocked the sports world when he signed a £12m a year deal with Italian brand Gucci back in April.
