Last year, Vicky shed three stone, dropping from a size 16 to a size 6 after embarking on a strict diet and fitness regime. Impressed with her results, Vicky's transformation motivated her co-stars to do the same, and after seeing unflattering pictures of herself in a bikini, Charlotte too embarked on her own weight loss mission.
Now having lost two-and-a-half stone, Char has been flaunting her new bod, but not without being compared to Vicky. Speaking out against rivalry rumours, she said: "Everyone is saying it's a competition or it's a battle... it's none of these things."
Speaking to Daily Mail Australia, Charlotte shrugged off claims there is a weight loss battle between herself and her pal - even crediting Vicky for motivating her to get into shape.
She said: "I don't think there is any competition... If anything Vicky inspired me to want to lose weight. When I was still a lot bigger she was always trying to get me to get involved in exercise and I'd just be sat there eating a sausage roll!"
Unhappy with her weight, Charlotte embarked on a healthier lifestyle, changing her diet and regularly exercising.
Unsurprisingly, the starlet soon saw results and encouraging others to do the same, Charlotte released her own fitness DVD 3 Minute Belly Blitz - which has now become the fastest-selling fitness DVD to date.
Now much happier with her svelte frame, Char - who rekindled her romance with ex-boyfriend Mitch Jenkins earlier this year - revealed she is now pleased with her body and doesn't plan on losing any more weight.
She added: "I am happy where I am now. I wouldn't want to lose any more... I [wouldn't] exist!"
Meanwhile in January, Vicky told Reveal she has "never been so proud" of Charlotte following her transformation.
Explaining she had trained Char and Holly Hagan while in the Geordie Shore house, Vicky told us: "I gave them tips and advice. We trained together."
She too slammed claims of competition between the girls, insisting each other's success is "motivation".
"There's nothing malicious," Vicky claimed. "It's motivation. It's like when your sister loses weight or your mates are on a health kick, it's a bit of solidarity. We will keep each other going."
