The 'Love Island' star has been urged to get a boob job after posting a picture of herself in a bikini on Instagram, while on holiday with boyfriend Adam Collard.

However, the feisty 21-year-old star hit back, calling the comments "disgusting".

According to the Daily Mirror, she said: "A disgusting thing to say. Why wish surgery on someone?I haven't got any other 'plastic' in my body by the way.

"If there is something I will never be able to accept about this industry, it's the hate people give out. People wonder why things such as anxiety and depression exist. This is the reason.

"Luckily, I'm strong enough not to cave in and get the surgery."

Adam clearly disagreed with the Instagram trolls, commenting: "I'm a very lucky boy."

And Zara also had to defend herself when another Instagram user insisted the bikini was too small to properly fit her boobs.

One person wrote: "Honestly babe, you can't really think that the bikini is in your size. Like just look at your t**s babe. It's not flattering at all. They loom like squished water balloons. No one will judge you for wearing a bikini top your actual size x just some advice xx."

A frustrated Zara hit back, saying: "I'm the one who has to wear it and honestly I think it fits absolutely fine... any bigger and it would have been too big. anyway I thought all you trolls were saying I have no boobs, now all of a sudden they're too big for my bikini. you all need to come to a group consensus about what exactly you're going to troll me about cos right now I'm confused (sic)."
