He was considered to be something of a heartthrob as a teen TV star back in the 90s.
And this 50-year-old actor, known for his luminous blond locks and cheeky boyish smile, now looks unrecognisable with his jet-black wavy long locks and a long beard.
Now a star of movies such as 12 Dates Of Christmas, Dead Man On Campus and Precious Cargo, the handsome chap has carved out quite a career for himself.
But can you guess who it is yet?
It’s Mark-Paul Gosselaar – known as Zack Morris in Saved By The Bell.

The actor captured the hearts of the nation when his debut show aired in August 1989 as he became the cheeky bad boy everyone adored.
Mark-Paul has now ditched his golden dyed locks, which were inspired by Vanilla Ice’s frosty tips, and has now embraced his naturally thick dark brown hair.
NBC’s Saved By The Bell became a fan favourite when it first aired in the US in 1989.
After airing every Saturday morning, the sitcom soon became a channel flagship and had several spin-off shows during the 90s.
The show proved to be his biggest success, as he is still pursuing a budding acting career after recently starring in Found, Will Trent and Missing While Indoctrinated.
Speaking to Jimmy Fallon in 2015, Mark shocked TV buffs after admitting that his hair wasn’t naturally blond.
‘People think, ‘Oh, that’s your natural hair color’ – it was not. That was color by Clairol,’ Paul said, as Jimmy held up a picture of the actor sporting bleached tresses.
‘That is not natural, guys, you can see the brown going through’, he added.

Mark also revealed that after every season the crew were sure they were going to be cancelled and so all said their wholesome goodbyes every year.
He said: ‘You know, our show, every year we thought we’d be canceled.
‘Every single season of Saved By The Bell, it was ”canceled.” At the end of season, we all left, we said goodbye to each other.
‘And that’s why every season my hairstyle was so radically different! Because I was just going to school, and I had the Vanilla Ice thing, cause Vanilla Ice was big in 1990, so I had the shaved sides and, like, the big bouffant.’
