Jesinta Franklin has revealed the odd food combination that she craved in the early days of her pregnancy. 

The AFL WAG, who announced her pregnancy on Tuesday in a sweet Instagram post, took to the social media platform to share her bizarre pregnancy cravings.

The 33-year-old admitted to being obsessed with pairing jalapenos with a slice of cheese.  

'Ate an entire jar of jalapenos in 2 days. The combo with cheese honestly just hit the spot in those early weeks.'

Weeks later, however, just thinking about the spicy food combination makes her sick.

'Now the thought makes me ill,' she confessed. 

She also praised another popular snack that no doubt tops people's go-to cravings. 

'Thank goodness for hot chips,' she wrote on one of her stories showing a cardboard box of fries in her hand. 

Jesinta and her husband Lance 'Buddy' Franklin revealed that they are expecting their third child together in an Instagram post.

In a candid video, Jesinta shared a silhouette of herself cradling her growing baby bump while her two children, daughter Tullulah, five, and son Rocky, four, played around her.

One segment showed Rocky kissing his mum's pregnant belly. 

'Tullulah & Rocky are getting a baby brother or sister for Christmas. The most beautiful surprise of all,' the model captioned her post.

She continued: 'Our hearts are full and yet, we share this news with deep sensitivity. I know that announcements like this can be incredibly hard for those who are walking the path of infertility or loss. My heart is with you, always.'

 It wasn't long before the joyous announcement was inundated with well wishes from the couple's famous friends.

'Ahh I had a feeling! So beautiful congrats x,' wrote actor Natalie Bassingthwaighte.

'Now THIS is a pregnancy announcement,' added comedian Celeste Barber.

'Congratulations ❤️ I'm so happy for you all. Beautiful news xx,' commented fashion designer Lana Wilkinson.

Sports journalist Abbey Gelmi, NRL WAG Kayla Boyd and fashion designer Pip Edwards also joined the chorus.

Following the announcement, Jesinta admitted the last few months have been taxing on her Instagram Stories.

'Looks cute but this person has given me a rough time the last couple of months,' she wrote alongside three sick face emojis.

'Sadly I'm not someone who thrives when they are pregnant.'

In another slide, the model shared a candid selfie pretending to be asleep.

'The reality of the last 6 weeks. House, couch or bed bound given the odd occasion. Finally succumbed to medication and it's been game changing,' she captioned the image of her resting beside Buddy.

She went on to express her gratitude and revealed the couple will be keeping the child's gender a surprise this time around, alongside an image of a pregnancy test.

'An absolute blessing,' she began.

'Even though we thought we were happy and done with two beautiful children, we have been lucky enough to add another to the family.

'Life works in mysterious ways and I'm leaning into this next chapter with a grateful heart.

'Lulu and Rocky are beside themselves and can't wait to meet their baby.

'Keeping the gender a surprise this time around,' she added.
