Amanda Holden was left completely stunned by Nativity! child star who looks completely unrecognisable 14 years after starring in the hit Christmas film.
Nativity! hit screens back in 2009 starring Martin Freeman as Paul Maddens, Jason Watkins as Gordon Shakespeare and Marc Wootton portrayed Desmond Poppy.
While some of the adult stars have remained in the spotlight in the 15 years that have passed, other cast members have carried on with their life out of the spotlight.
And one of the most memorable character's Bob in the film was played by Ben Wilby, who defied the odds to beat a severe health condition to star in the film.
The Staffordshire-born star, who is now 22, stunned Heart radio presenter Amanda during a cameo on her breakfast show last year.
The Britain's Got Talent judge was tasked with overseeing auditions for Heart's Big Christmas Show with famous faces including co-star Ashley Roberts, as well as Tom Fletcher and Leona Lewis, performing and Ben made a surprise appearance.

One of the most memorable character's Bob in the film was played by Ben Wilby, who looks worlds away from his younger self
Ben, donned a white top and jeans took to the stage and announced: 'Hey Amanda, I'm here to audition for your Christmas show. Don't worry, I've done it before'
Ben is most memorable from the iconic scene where he started break dancing in a bid to get to Hollywood and he proved he's still got it.
Ben, donned a white top and jeans took to the stage and announced: 'Hey Amanda, I'm here to audition for your Christmas show. Don't worry, I've done it before.'
Baffled, Amanda, who was dressed in all white and rocked a Christmas hat, questioned: 'Where do I know you from?' before he performed his dance routine.
She squealed: 'Wait, OMG,' as he said: 'It's me, Bob from Nativity!'
He then burst into song, chanting the lyrics: 'She's the brightest star I've ever seen, brightest star.'
Ben then begged to go to Hollywood, to which Amanda said: 'Hollywood is going to love you.'
He cheered: 'Get in there baby, get in,' before scooting away.
However, Ben has had to overcome a lot in his life since the film - with doctors warning he may never walk or talk after a nine-hour operation as a child.

The 2009 film also starred Martin Freeman as Paul Maddens (R) and Marc Wootton portrayed Desmond Poppy (R)
He was diagnosed with Craniosynostosis, a birth defect in which the bones in a baby's skull join together too early, when he was just two - with doctors warning his parents he may not survive a procedure to relieve pressure on his brain.
But Ben defied the odds and joined a dance school to develop his balance and improve the strength in his legs. He went on to win a number of trophies, including the title of European Freestyle Champion.
Determined to live life in the limelight, Ben then beat 500 other young hopefuls to win the role of Bob in the hit film, Nativity, having turned up to the auditions wearing an audacious outfit of neon green shorts, legwarmers and a t-shirt with the slogan 'Born To Dance' on it.
After his appearance in the film, Ben, now 19, went on to feature in two other Nativity! movies, as well as appearances in television series' Father Brown and Cuckoo.
Nativity! follows loveable primary school teacher Mr Madden who tries to put on the best nativity play with his class after claiming that Hollywood are coming to visit.
The movie centres around the pupils of St Bernadette's Primary School, who were practically infants when the film first hit screens.
