TOWIE star Harry Derbidge signs up to Celebrity SAS: Who Dares Wins

Harry Derbidge has signed up for the upcoming series of Celebrity SAS: Who Dares Wins, MailOnline can reveal.

The TOWIE star, 29, will compete in the grueling Channel 4 show to be filmed in New Zealand this month and has ambitions to overcome the physically demanding challenge.

He joins reality TV personality Bianca Gascoigne, 36, in the lineup of stars who leave their lives of luxury behind and are pushed to their limits during the intense process.

A TV source told MailOnline that Harry, who was just 16 when he first rose to fame on the ITVBe series, is hoping to face his demons as he is mentally tested by Billy Billingham, Jason Fox, Rudy Reyes and Chris Oliver.

“Harry is determined to prove people wrong,” an insider said. “Obviously he loves his glamorous life, but that doesn’t mean he won’t do anything to get all the way into the show.”

Harry was first introduced to TOWIE through his cousin Amy Childs and became the show’s first openly gay cast member.

The makeup artist has enjoyed several spells in the series, but can still consider herself a “TOWIE original.”

In 2012, he launched a unisex jewelry line called Love Lemonade with Amy and has since boosted his bank balance by releasing a range of lashes and eyeliners through his cosmetics company, Beauty Brave.

He is currently embracing the fact that he is an uncle to Amy’s newborn twins, who will appear on TOWIE this series for the first time as the cast movie of the latest installment in Cyprus.

Amy, who is also a mother to daughter Polly and son Ritchie, gave birth to the twins in April after falling pregnant with boyfriend Billy Delbosq.

During last season, Harry began dating co-star Junaid Ahmed after the two considered taking their friendship to the next level.

It was decided between them that their relationship would not work romantically, with Harry telling his family that he just sees Junaid as a good friend.

Harry previously dated his former co-star Bobby Norris and was also engaged to ex-boyfriend Dean Rowland before they split last October.

During the final season, which also stars Chloe Brockett, Harry began dating co-star Junaid Ahmed after the two considered taking their friendship to the next level.

In March, Harry shared a photo of himself taken 13 years ago alongside a photo of his body taken today, as he talked about his eating disorder.

The TV star recalled feeling tired and lethargic as he struggled with the disease, but told followers he is now healthier than ever and proud of his figure.

He said, “If you’ve been following me for a while, you know I struggled with an eating disorder when I was young and I’m so thankful to say I overcame it with the help of my family and loved ones.

“I’m the healthiest I’ve ever been. 13 years ago I had no energy, had trouble eating and hated wearing clothes. 16-year-old Harry would be so proud of how far I’ve come.’

In May, it was revealed that Channel 4 SAS: Who Dares Wins is shutting down after eight series after its 2015 launch.

The celebrity spin-off of the show continues, but the civilian version has been given a go amid reports that the broadcaster is overhauling many of its long-running shows.
