Shortly after landing in Brisbane, the now-MMA fighter started opening up about wife Chloe Madeley, 32.
But who is she, how did they meet, and do they have any kids together?
Here's the lowdown on their relationship so far...
Who is James Haskell's wife?
Rugby player-turned-MMA-fighter James Haskell has been married to journalist and model Chloe Madeley since 2018.
As well as being a fitness fanatic, Chloe is the daughter of daytime TV legends, Richard Madeley and Judy Finnigan.
She has also published three healthy recipe books, modelled and dabbled in TV presenting and journalism over the years.
You may have also heard Chloe's fitness podcast, entitled Bodcast, which features interviews with fellow fitness enthusiasts.
Since James entered the jungle, Chloe has been sharing sweet snaps of her and her husband with her 198k Instagram followers.
Before his I'm A Celeb debut, she wrote: “When you go through a lot with someone you end up somewhere remarkable. I couldn’t be prouder of you @jameshask.”
How did James Haskell and Chloe Madeley meet?
The loved-up pair reportedly met through social media back in 2014, and dated for four years before tying the knot.
Chloe revealed to Hello that James got down on one knee and proposed to her in Paris, saying: "He kissed me on the forehead and said, 'You do know how much I love you, don't you? The last three and a half years have been the best years of my life.'
"I just thought he was being romantic because we were in Paris, so I replied: 'Oh babe, that's so sweet.'
"But then he added: 'And you do know I want to marry you?' and started to get down on one knee."
She added: "At first I thought he was joking. I was speechless and stared at him in disbelief."
Where did they get married?
The couple got hitched at the All Saints church in Berkshire on December 15, 2018.
According to Chloe, they were inspired to have a traditional ceremony after attending the Royal Wedding that year.
She wore a gorgeous V-neck gown by Pronovias, with an embellished white lace top and elegant satin skirt and teamed the look with loose curls.
James donned a dapper navy suit with a grey checked waistcoat and festive red tie.
Do they have any children?
While the couple do not currently have any kids, they have spoken about their plans to start a family in the near future.
Discussing their change of heart with Hello magazine, Chloe said: "We've gone from one end of the spectrum, where we didn't want children, to the other end where we thought, 'yes, let's try it'."
She added: "Now we're in the middle, contemplating it as a reality. James is made to be a father. He'll be a brilliant dad."
How do James and Chloe know Meghan Markle and Prince Harry?
In May last year, the couple attended the wedding of the year - that of Meghan Markle and Prince Harry.
Chloe and James stepped out in sunny Windsor in a nude summer dress with a gold tassel belt and a smart navy suit respectively.
It is well-known that Prince Harry is an avid rugby fan, as well as a patron for the Rugby Football Union, and has met James on many occasions through the sport.
The sports star was due to play with his team the Wasps that day, but decided to attend the Royal Wedding instead.
The decision to desert his teammates angered some, with BT Sports pundit Lawrence Dallaglio commenting: “It would be poor form really, wouldn’t it? He should be here with his teammates. I’m sure Harry wouldn’t mind, he loves his rugby anyway.”
