Shane Warne's son Jackson, 25, competes in a poker tournament in Las Vegas alongside longtime girlfriend Kiah Broadsmith

Jackson Warne, the son of the late Australian cricketing icon Shane Warne, showed his talent in a different kind of game this week.

The 25-year-old competed in a poker tournament in Las Vegas on Wednesday.

Jackson wasn't flying solo for his Vegas trip, with his long-time girlfriend Kiah Broadsmith at his side to lend her support and good luck charms. 

Jackson cut a casual figure for his big day on the tables, wearing a plain black T-shirt underneath a grey puffer jacket.

Perhaps wanting to disguise his wealth, the cricketing scion complemented his ensemble with a pair of plain black chinos, tall white socks and a pair of brown slides. 

He finished his look with a white baseball-style cap that featured a black heart in a little nod to his favourite game. 

Kiah, meanwhile, was similarly rugged up in a plain white hooded jumper.

She kept the casual casino vibe going with a pair of black cargo pants and a pair of well-worn Adidas trainers.

Before the tournament kicked off, the young couple were spotted sharing a knowing smile as Jackson waited to take his seat.

Kiah looked every inch the supportive partner, beaming at her beau as she wished him luck. 

But then it was time for the main event, and Jackson wore same grit and determination on his face that his famous father was known for.

Rolling up the sleeves of his jacket, he appeared keen to show everyone that he came to play.  

Jackson was the embodiment of the term "poker face", sporting a stoic expression as he looked around the table, sizing up his competitors.   

Jackson and his partner Kiah went public with their relationship in December, 2021.

 Shane, who died one year later in 2022, was able to get to know his son's girlfriend before he passed. 

Shane once commented on an Instagram snap of the young couple: 'Awwwww love you guys.'

The legendary leg spinner died on March 4 at the age of 52 while on holiday with friends on the island of Koh Samui, Thailand.

An autopsy concluded he died from 'natural causes'.

Jackson's poker outing comes after he revealed a shock new career move in October.

He revealed, via a promotional photo shoot that he was the face for SAINT, the little brother to $150 million private members wellness club, Saint Haven. 

 'If you’ve been following me for a while, you know how passionate I am about health and wellness, and this is hands down the best place in Melbourne to elevate both!' he wrote in the promotional post.

Saint Haven is a chain of private members clubs in Melbourne owned by millionaire property developer Tim Gurner, who made global headlines in 2023 after calling for a 'painful' 50 per cent increase in unemployment to spur 'lazy' workers into action.

That came after the rich lister wondered aloud that 'arrogant' employees needed to 'feel pain in the economy,' last September.

The exclusive Saint Haven and SAINT clubs are a cross between mysterious elite members clubs like American SoHo House - which announced plans to open an outpost in Sydney last year - and Nicole Kidman's wellness retreat in TV drama Nine Perfect Strangers.

Members of the New Age health spa follow Gurner's regimen of biohacking and anti-ageing processes.

Several rushed to snap up 500 limited memberships to Saint Haven in 2023, with a price point of up to $1000 per week. 

Prospective members had to complete a five-stage application process to apply for the rich man's fraternity house, including undertaking numerous medical tests.

Jackson's appointment as an ambassador is part of the multimillionaire's grand plan to extend the reach of his three sites, in Collingwood, South Yarra and Toorak, to a younger demographic.
