Duncan James looks unrecognisable from his Blue days as he delighted fans with a topless snap.
The singer and actor, 43, took to Instagram to upload the racy picture with his 388,000 followers, revealing he had been trying to transform his physique ahead of his upcoming 44th birthday.
In the mirror selfie, Duncan is posing in just a towel in the locker room at the gym, and he can be seen pouting at the camera with his impressive chiselled six-pack on show.
“Not too shabby for nearly 44,” he wrote in the caption.
“Started this year on a juice cleanse with @presscriptionjuice and back training with @ciaranoconnell to help me get ready for the big year ahead. #newyearnewme #juicecleanse #fitnessmission2022 #fitat40,” Duncan added.
The transformation impressed his fans and followers, including Christine McGuinness, who commented: “Big Dunc,” alongside a heart eyes and flame emoji.
Other famous friends including Ashley Roberts and Lizzie Cundy were also quick to heap praise on his muscles, and his fans were left flustered with the saucy changing room snap.
“Fit!” one wrote, as another agreed: “Gorgeous.”
“Actually the hottest guy alive,” another wrote, as one fan commented: “There’s no need in being this beautiful, where can I order one of him?!”
“Looking amazing duncan,” a fan added, with one follower commenting on his age-defying good looks.
“Definitely look younger than 40 something!” they wrote.
He also gave one of his fans tips on how to shed the pounds, after they asked how they could shed their “mum tum”.
“Looking good Duncan! Any tips for this second time mum with a massive mum tum coming to see you guys in sept,” she wrote.
“stick some blue on and dance around the house. see u in sept xx,” Duncan sweetly replied.
The Real Full Monty star has been showcasing some dramatically different looks recently, which are a far cry from his clean-shaven look during his early boyband days.
Duncan shocked his followers earlier this month when he posted a throwback photo of him with long curly hair, prompting him to joke he looked like Jason Momoa’s Aquaman.
