He's never been shy to admitting he's been approached by producers to star on this season of I'm A Celebrity... Get Me Out Of Here!
And now, actor and activist Samuel Johnson has dropped the biggest clue yet he's jungle bound.
On Wednesday night, the TV WEEK Gold Logie winner uploaded a very telling photo from the airport alongside the caption: "My second home... ...airport carpark... ...costs more than rent but the views are superb..."
And it didn't take long for fans to go wild with speculation that the Love Your Sister charity campaigner may just be headed to South Africa.
"Let's hope you are off to Africa I never watch but will if you are on," one user wrote.
"So excited to have you back on our telly! Proud of you already! You got this 🤗 just be you we love ya guts so much Sammy❤️ Good luck Matey! Xxx," another follower added.
"Soon your resume will read: Samuel Johnson, Gold Logie Winner, Victorian of the Year, King of the Jungle," a third penned.
In November, Sam opened up about the reality show to Kyle and Jackie O on their KIIS FM radio show, admitting he was flirting with the idea.
"I might be making a very stupid decision next year, but I haven't signed yet, so I can't say anything," Sam said.
Adding: "We're talking reality. I've never done it in 25 years, but I'm so desperate to get to the 10 million, I'll do anything."
Then in December, he stoked the fires even more when he uploaded a newspaper article about his potential foray into the jungle - but this time he asked his devoted fans if he should take the plunge, and the response was overwhelmingly positive.
"Thoughts about doing reality t.v. for the first time please? Xsam," Sam asked on the Love Your Sister Instagram account.
"Australia needs a REAL reality personality and just think of the exposure and ability to talk about real stuff. It could change the world. Seriously," one fan encouraged.
"You rode round the country on a freakin unicycle!! Reality TV would be a walk in the park for you. I'm a celeb would be my pick, only cos you don't baulk at a challenge & would seriously kick arse! I say go for it," another mused.
"Would absolutely love to see you be the king of the jungle on "I'm a celebrity, get me out of here". You'd raise a bucket load of cash from all the votes and then win the major prize for sure. All Australia love you, and the love your sister army would "vote vote vote". Go for it Sam," a third agreed.

That same month, Sam also posted a photo to Instagram of his signature on a mysterious contract. "Here goes nothing," the 40-year-old cryptically wrote.
If Sam does indeed take up the offer, it would be a huge coup for network Ten.
In 2016 after winning the TV WEEK Gold Logie Award for his portrayal of music icon Molly Meldrum on Seven's mini-series Molly, Sam famously announced he would be retiring from his successful acting career until he raised $10 million for breast cancer research on behalf of his big sister Connie, who tragically passed away from breast cancer in 2017.
Meanwhile other high-profile stars like Karl Stefanovic, Nick Cummins and Pamela Anderson have also been tipped to star on the show.
The full cast will be revealed on the season premiere this Sunday, January 13 on Channel 10.
