Gregg Wallace is unrecognisable with a full head of hair in a snap taken when he was "young".
The MasterChef judge, 58, shared the photo with fans on Instagram - but many of them didn't know who it was.
Captioning the snap "Young Gregg", the famously bald foodie looks a world away from his days on the BBC cooking show sporting thick, dark hair.
After clocking the transformation, one of Gregg's followers exclaimed: "Wow! So different!"
Another said: "Looks nothing like you!"

Gregg shot to fame on MasterChef with John Torrode - and is not short of female fans.
He has been married to Anne-Marie Sterpini since 2016 and the father-of-three claims the younger woman, who is 22 years his junior, has 'revolutionised' his life.
The pair met in 2013 when Anne-Marie, 36, tweeted the famous foodie to ask a cooking question.
The keen cook, who would have been 26 at the time, asked Gregg if rhubarb really went with duck, after seeing the star test a recipe on TV.
Gregg told HELLO! Magazine: "I just looked at Anna's photo and thought, 'Wow, she's pretty'. So yes, rhubarb, which was considered an aphrodisiac in medieval times, brought us together."
He later shared more about their love story while appearing on ITV's Lorraine, revealing he sent the Italian a message on Twitter, which kicked off their relationship.
"Then I sent her my phone number, this was five years ago," he confessed at the time.
However, Anna wasn't 100 percent certain Gregg was the real deal until they met up for the first time in person.
"She came down to London to have dinner with me, and she said it wasn't until we got to the restaurant, that she was comfortable it was really me and not an impostor," the presenter admitted.

Gregg revealed Sid's autism diagnosis last year after realising the toddler was having difficulty communicating.
Speaking about how the condition affects the family, the presenter told Loose Women last week he and Anna were "really worried" because their child can't tell them if something is wrong.
However, Gregg did say Sid, who he adorably calls 'Squid', is making progress, including being able to give his proud dad a high-five.
