Jesinta Franklin has finally revealed the adorable - and very unique - name of her newborn son, whom she and her AFL star husband Lance 'Buddy' Franklin welcomed in December.

The glamorous model, 34, posted a photo of her tenderly cradling her bub as they relaxed at home.

'Me and my little sidekick, Bam. He's been on every Zoom, attended every meeting, every photoshoot and now, every podcast I've done since he was born,' Jesinta wrote in the caption. 

'It can be tricky finding the balance between it all, but this guy has made it so easy for us. He doesn't leave our side... just rolls with the chaos that is our life!'

Many of Jesinta's celebrity friends took to the comment section to gush over the sweet name and photo.

'Hi Bam's mum,' wrote Celeste Barber.

'Angel,' added Aussie model Rachael Finch.

Buddy and Jesinta welcomed their third child on the Gold Coast in December.

Jesinta confirmed the exciting news on social media, by sharing a precious gallery of photos.

One adorable black-and-white picture captured the couple happily posing in a mirror selfie as Buddy, 39, tenderly cradled their newborn in his arms.

Another photo showed the infant resting peacefully with Jesinta, who lovingly held onto her baby.

The glamorous model captioned the gallery with some exciting words: 'My heart feels like it could burst.

'Home for Christmas with the most special gift of all.'

Jesinta recently opened up about the downside of pregnancy as she prepared to welcome baby number three.

The model and her husband Lance are already proud parents to daughter Tullulah, five, and son Rocky, four.

Speaking to 7News at the event, she admitted that her pregnancy had not always been plain sailing.

'I spent about 10 weeks on the couch and that was pretty hard,' Jesinta said.

Jesinta added that she was 'grateful' to have got through what had been a hard first trimester.

'I am so grateful and thankful, but it's nice to have come out on the other side,' she said.

It was a similar sentiment that Jesinta shared after announcing her impending arrival.

She admitted on her Instagram Stories that the last few months had been taxing.
