Lateysha has said the nasty dig, which was made in last week's episode of the MTV reality show, has now left her "questioning her figure", despite being a healthy size 10.
The Welsh reality star said: "When Nicole said I had a big fat belly it really hurt. No girl, especially your friend, should ever attack your weight or how you look.
"It led me to question how others picture my figure.
"II'm a size 10. There is nothing unhealthy about that. I've got a big bum, which I love, but I work hard for it and spend endless hours in the gym."
Lateysha spoke out while launching her S/S '14 clothing line Lateysha Loves and also admitted that she is considering a nose job.
"I've had some help with a boob job and nipple correction, which was really needed, and I've also had my teeth fixed with veneers," she added.
"It's all cost a lot of money, about £15,000 up to now, but it was worth every penny."
Lateysha added: "I do think I want a nose job at some point in the future, I'd love a slim nose like Beyoncé's.
"We have a similar colour skin tone, and her nose suits her face perfectly. I'd take a picture of her to the surgeon and ask him to copy her nose."
We think you look great as you are, Lateysha!
