Claudia, 28, has lost nearly three stone in recent years but admits she still struggles with her looks sometimes when she looks in the mirror.
Speaking on a new podcast, the stunning reality star admitted, “I feel like I’ve never been a confident person.
“Everyone sees me as this funny, happy, sparkling ball of energy.
“I will never show how I actually feel and sometimes I feel very insecure.”
Claudia opened up to fellow Love Island alumni Scott Thomas for his podcast Learning As I Go.
The gorgeous blonde, the daughter of superbike champion Carl Fogarty, told Scott she had reached her heaviest weight after a breakup three years ago.
Claudia revealed: “I looked in the mirror and thought, ‘What are you doing?’ I was a lot heavier and didn’t feel comfortable in my skin, I just let myself go.
“People always say, ‘I didn’t know you were taller’. But in photos I was always hiding, I was in the middle and I had a way of being in a photo and editing it.
“I didn’t want people to see how tall I actually was. It wasn’t until I took a picture with no clothes on and literally saw the raw picture of me that I thought, ‘Oh my God’.”
Claudia said things “clicked” during a session with her personal trainer and she embarked on a lifestyle review.
“I said ‘I’m tired of feeling bloated and fat’ I’m not saying I was fat because people will look at the pictures and I’m not and I was just really round but it was more for my health,” she explained.
“I started crying, she started crying and even my mother started crying.
“That day I started my own journey. It’s been three years now.”
The star, who was dumped next to Love Island’s Keanan Brand, almost lost three stone as a result of the changes she made.
She started walking more, went to the gym and switched chocolate for fruits and nuts.
Claudia also said cutting back on booze helped, as she no longer suffered from hangovers and mocking junk food.
But she admitted, “It’s hard for me to be just one weight. It’s constant, but it’s a lifestyle change.
“It’s hard and don’t think I’ll ever come to terms with it. It’s a struggle.”
Claudia made her heart beat faster when she entered the South African villa during the infamous Heart Rate Challenge.
The blonde bombshell paraded out into the garden, dressed in sexy red lingerie and giant Victoria’s Secret-style wings.
However, despite her sizzling looks, Claudia admitted she was terrified and had previously insisted she wouldn’t go on the ITV2 show that way.
“The one thing I didn’t want to do was take that challenge,” she told Scott.
“I told my mom before I went. I was like ‘Please, I hope they don’t do this to me’.
“They surprised me with Ann Summers lingerie and wings. I was like ‘Are you really laughing?’
“Asked me a few years ago and I wouldn’t have done something like this in a million years.”
