Following his 2019 appearance on Dancing With The Stars and after months of dating rumours, Jett confirmed he was in a relationship with his dance partner Lily Cornish.
The dancing duo turned heads from the very first episode, with producers playing up the couple's sizzling onscreen connection, and even co-hosts Grant Denyer and Amanda Keller frequently making references to their undeniable chemistry.
Jett spoke to Sydney Confidential at the time, saying it was hard to be apart from Lily while she worked as a dancer on a cruise ship.
"She's working on a cruise ship for four months. Four months separated and she... doesn't always have phone reception," he shared.
"You mean his dancing girlfriend," responded Lisa, using an illuminating choice of words.
"Young love… there’s nothing to report," she added, pointing out that Lily was working on the other side of the world for four months, while Jett remained in Australia.
"I did say if there’s any news, make sure I know first."
Jett even fuelled engagement rumours after he shared a cosy snap of him and Lily arm-in-arm at Sydney Harbour.
"Not sure if I’m going to last four months without annoying you daily," Jett said in the caption.
Their intimate public displays spoke volumes, and family friends in April 2019 confirmed to Woman's Day that Jett had fallen hopelessly in love with Lily, who was 20 at the time.
"Jett hasn't dated a lot since high school, so the fact he's fallen so hard for Lily has taken everyone by surprise," a close family friend revealed, saying Lily was welcomed into the Kenny-Curry clan.
"He's trying as hard as he can to make it work, but it's tricky because she lives in Melbourne and he lives on the Sunshine Coast."
Jett's famous mum was reportedly playing Cupid behind the scenes so Jett didn't let his Dancing With The Stars partner slip away.
"Lisa is Lily's biggest fan and really wants it to work out, so she's gone all out to make Lily feel welcome and a part of the family," the friend claimed.
But Jett and Lily's whirlwind romance didn't last and the pair parted ways in around May 2019.
In October 2019, Jett's love life was back in the spotlight when rumours began to circulate that he was romantically linked to billionaire heiress Francesca Packer, the niece of business mogul James Packer.
