He's made his name as the legendary DJ Fatboy Slim.
But the star's physique couldn't be any further from his Fatboy name as he showcased his chiselled abs in a throwback magazine snap.
The DJ, real name Norman Cook, turned 63 at the end of last month and marking his birthday his son Woody took to Instagram as he shared the resurfaced snap.
Norman went shirtless on the October 2000 edition of Mixmag magazine as the headline read: 'Want some Fatboy? Tanned, rested and ready Norman's back in the ring.'
In a sweet tribute Woody penned: 'HAPPY BIRTHDAY DAD. You’re an alright DJ, but a much better Dad. Thank you for giving birth to me.'
Earlier this week Norman sported a rather different look as he dressed up as a giant pack of fish and chips for his show at Bestival in Dorset.

Setting the crowd wild, Norman dressed up as a giant pack of fish and chips while performing his set before working up a sweat while he blew on an airhorn at the record-breaking final day of the festival.
On the final day of the festival, he held a Fatboy Slim & Friends All Day Castle Stage takeover, in which he was curating a number of acts including The Beat, Brooke Coombes, Fat Tony and De La Soul.
Norman shares son Woody, 25, and son Nelly, 16, with his ex wife Zoe Ball and despite their split the couple still get on as great friends.
The former couple tied the knot in 1999 but briefly separated after Zoe, 55, admitted to an affair with fellow DJ Daniel Peppe.
However, they managed to patch things back up just three months later, until their divorce in 2016.
Despite their separation, the pair have remained close friends and Norman has said his 'triumph' is that they've remained really good friends and parents, but admitted it was 'a bit awkward at first'.
Speaking to Davina McCall on her Begin Again podcast back in June, Norman revealed that their greatest achievement is how they've kept such a good relationship after their split – something he is proud of.

He said: 'Going through it together was great because, Zoe is a really good teacher, she was really good, really measured and she's kept me really grounded to earth…
'She is, and still is, we're still really good friends.
'Our triumph is to remain really good friends and parents, even though we're not a couple anymore...
'It was a bit awkward at first, but then we got this rhythm where… we're probably actually better than we were when we were a couple.'
He added: 'You sign on to be parents, that's for life.
'You can sign up for marriage and you can get divorced. But you can never stop being parents.'
