Aussie model Simone Holtznagel was deep in the South African jungle, filming Channel Ten's reality show I'm A Celebrity Get Me Out of Here!, when she was called fat by a male radio host.

Two weeks ago, Triple M's Mick Molloy compared 24-year-old Holtznagel, who has appeared on the cover of Playboy magazine and modelled for US clothing brand Guess, to a baby elephant.

The story was reported by every major media outlet and Molloy was forced to apologise.

His response included an acknowledgment of his own lacklustre appearance: "[I'm] ... known as an idiot and ... happen to be as fat as a house."

Speaking to news.com.au from her hometown of Wollongong in NSW on Friday, Holtznagel laughed when asked about how Molloy's comments made her feel.

"I thought it was hilarious. Like seriously, if I'm going to take modelling career advice or any advice on fitness, he's not going to be the person I take it from," she said.

"I did see that he's now gone on a health kick. Apparently he's been so fat shamed since saying that about me that he is now going on a diet. Now I guess you know how it feels."

Holtznagel is not yet a household name like fellow Aussies Elyse Knowles or Jesinta Franklin, but she's been working consistently as a model for the past 10 years.

"I would love to do Sports Illustrated [magazine]. That's my goal," she said.

In 2011 at age 17, she was named runner-up of Australia's Next Top Model and developed a close relationship with the late Charlotte Dawson, who was one of the judges on the show and took her own life in 2014.

Holtznagel decided to go on I'm A Celebrity to raise money for mental health charity Beyond Blue.

She flew back home from South Africa on Thursday and is gradually settling back into normal life.

"I tell you, I reckon my stomach is still recovering from eating all those cockroaches," she said of the show's gross challenges, requiring contestants to chow down on insects and obscure animals.

Her first meal after elimination was "ravioli with pesto" and she popped a bottle of Moet champagne with her co-stars and their families.

"Now after getting out, it's so weird being back home. I feel like I just got out of jail," she joked.

"I do know that this morning when I woke up, I thought 'I wouldn't have minded waking up in the jungle'. But I'm just taking my time getting back into normal life, just chilling out."

She's currently enjoying a career high as the face of Bras N Things, with her incredible figure plasted over the chain's store fronts around the country.

"Yesterday I came home from the airport and went to the shops to get a few things and I went into Bras and Things and saw the pictures. It's weird, but I guess it's pretty cool.

"I remember first seeing my Guess billboard in LA [she is an ambassador for the brand].

"I got out of the car and this guy was looking at me weirdly. He looked at the billboard, looked back at me and he said 'Is that you?'. And I was like 'Yeah mate' and he said 'Congratulations that's awesome'," she recalled.

"At first I was kind of embarrassed. It was on Sunset Boulevard at this big intersection I was like 'Oh my god this is so embarrassing', but then I was like 'Actually, f**k it, that's me on a billboard. I'm going to take some pictures. I don't care if people think I'm weird'."
