HER bee-stung pout is one of her trade mark features.
But while some believe Roz Purcell's luscious lips have been enhanced with fillers, freezers or injections, the 22-year-old says she's all natural.
And she doesn't plan on going under the needle anytime soon.
"It's funny because I get asked about them so much," the model said.
"It doesn't really bother me. I kind of learned to take it as a compliment. And, they're actually real.
But Roz wouldn't rule out surgery in the future. "Oh my God, never say never. When I'm like 50 or 60, I could be like a cat-woman. But I doubt it. I don't think I'd ever get anything surgical done, that's scary."
Most models live a glamorous life filled with parties, champagne and famous friends.
But Roz says that's not for her, instead she prefers quiet nights in and cycling.
"I'm in bed by 10 most nights.
"As soon as I go home I, like, take all the make-up off and go cooking, or cycling.
"When you're constantly around people, they expect you to be a certain way, then when I go home I need to do everything that chills me out; the most therapeutic things I can think of. I used to worry about work but now I've become really chilled. What has definitely helped is that I always get out in the fresh air."
"I suppose in college, like everyone, I did drink a little bit, but I never actually really enjoyed it. If my friends were going for cocktails, I would rather a Diet Coke or a cup of tea."
Roz has been romantically linked with Voice Of Ireland coach Bressie for over a year. But despite all the headlines and rumours she insists they are just good friends.
"I'm not in a relationship with Bressie. We're really good friends. I'm really private about my personal life and I'd rather not talk about it. Once I started travelling, you can't really have a boyfriend. And also, I don't think I'd have time to fit in one."
Roz told how her recent run-in with a mugger was "a lesson learned".
A thief grabbed her mobile phone as she made her way to the gym and while she gave chase for a while she eventually thought better of it.
The mugger snatched the phone from her hand, pulling the attached earphones out of her ears.
She ran after him but he disappeared into a flat complex and she decided to stop there.
The model says it was a shocking experience and it wasn't nice to be sitting at home alone afterwards with no way of contacting anybody.
