Jesinta Campbell on pregnancy rumours

Jesinta Campbell has fallen into the Jennifer Aniston and Cameron Diaz celebrity category.

No, she hasn't taken up acting or become an overnight American sweetheart. Instead the Australian model is the centre of ongoing speculative reports that she is pregnant with her first child.

The stories began last week when the 24-year-old, who is engaged to Sydney Swans player Lance 'Buddy' Franklin, 29, was pictured in a "billowing" top and puffy jacket with the accompanying headline, "What are you trying to hide?"

But the recently announced Olay ambassador laughed off the rumours when speaking to Fairfax Media on Thursday at the Sydney launch of her first commercial for the brand's Total Effects range, putting any alleged baby bumps down to bad camera angles.

"[It's] a bad photo," she laughed as she sat back in her chair and patted her taut stomach. "A baggy T-shirt and a bit of wind blowing."

Known for her laid-back and friendly personality, she said she doesn't mind such reports, explaining: "It's part of the parcel that comes with this [job]... Sometimes things upset me but the good far outweighs the bad.

"For me it's water off a duck's back."

While she's OK with hunches on her own impending motherhood, she said it's an issue that can deeply affect other women who have issues with conceiving.

"It's a really sensitive question for women - that's why I would never ask a woman about it because you never know what is happening," she said.

When asked what Buddy's reaction to it all was, she laughed again: "Just crazy, that is our life."

For the beauty launch lunch at The Butler in Potts Point, Campbell wore a Grecian style, white, flowing, floor-length Bec & Bridge dress that the Daily Mail claimed was "shapeless" insinuating, yet again, that she was trying to "hide" something.

She accessorised with a mustard-coloured, gold chained Chanel handbag and her estimated $100,000 engagement ring, given to her by the AFL star in December 2014.

It was said the pair had planned to wed at the end of last year, but postponed the nuptials after Franklin sought help in September 2015 for an unspecified mental illness and "a mild form of epilepsy".

While Franklin is back in good health and playing on the team, the wedding is on hold for now.

"It's just so busy at the moment. I am just focusing on work... I am just focussing on my career at the moment," she said.

That career includes an upcoming lifestyle book with 60 gluten-free, wholesome recipes, a four week training programme, a goal setting section, beauty tips and some behind-the-scenes secrets from her beauty pageant days.

She also recently signed with global model agency IMG, who have the likes of Gigi and Bella Hadid, Lily Aldridge, Joan Smalls, and Martha Hunt on their books, telling Fairfax Media she has been using "the last few weeks" to get to know the Australian team in the Martin Place office.

Starting off in pageants, the Miss Universe Australia 2010 winner said she never would have believed she would be working where she is today.

"I look back on when I first moved to Sydney as a 17-year-old. I had a scholarship at Bond University, so my intention always was just to have a gap year and to go back and study, back then if you would have asked me, I would have said I was just giving everything a try and wanting to have fun and experience a little bit of life and to end up here seven years later is another pinch me moment," she said.

It had been suggested her recent switch from manager Sharon Finnigin to publicist Annie Kelly, who also looks after Miranda Kerr, Lara Bingle and Shanina Shaik, means she has her sights set on lands further afield than Sydney, but Campbell denied such ambitions.

"My primary focus is Australia," she said. "There is so much going on for me here. I've got the two shows for David Jones, they can be pretty busy, especially spring/summer - a lot of training goes into that one."

When pressed on whether she had dreams of walking the Paris, London or New York catwalks, she added: "I have learned to never, ever say never but definitely not in the near future."

She described being signed as an ambassador for Olay as another "pinch me moment". "Especially for a woman in this industry, to get a beauty deal is a really big thing," she gushed.

Campbell said Olay was the perfect fit for her as it is a product that's "really special and it is respected globally".

Before she signed on the dotted line, she took some samples home and tried them out because "your skin can react differently" and she didn't want to promote something that she didn't love, but she said she was head-over-heels in love with the brand.

Her skin tricks include double cleansing her face after a day in makeup, wearing BB cream to prepare her skin and using coconut oil to gently remove eye makeup.

"It is so much more sensitive for around your eyes and so much more hydrating too," she said.

She has noticed some signs of aging, including "dryness", "dullness" and a "few fine lines", but always planning ahead she has already asked her facialist for advice on how to stay looking good in her "50s, 60s and 70s".

"I'm turning 25 this year, I need to start thinking about it now," she said.
