The Gogglebox favourite was pictured at Brisbane airport on Monday (7 November) alongside a slew of other famous faces all headed to the jungle.
Also spied were former footballer Wayne Bridge, presenter Lisa Snowdon, Strictly Come Dancing star Ola Jordan, Diversity's Jordan Banjo and Team GB hockey star Sam Quek, as well as I'm A Celeb hosts Ant & Dec.
ITV has yet to confirm the official lineup but when the stars start arriving in Australia it's pretty obvious who is entering the jungle, right?
Scarlett, 25, has been linked to I'm A Celebrity for absolutely ages, with a source telling The Sun in September: "They think she can be a better version of Vicky Pattison, who unexpectedly won last year's show... Also it's win-win as she'll look great in a bikini so will give them the much sought-after waterfall shot they want every year."
D'ya reckon the Moffatt family on Gogglebox will be seen watching Scarlett in the jungle?!
Former footballer Wayne Bridge was beaming as he walked through the arrivals at Brisbane on Monday. The former footballer is married to Frankie from The Saturdays and they have two sons.
An insider told The Sun last week: "Wayne never really sought fame when he was a footballer so it's surprising he agreed to go in the jungle. But ITV believe they've made a real coup getting him on board as he's never discussed the John Terry scandal before."
John Terry was accused in 2010 of having an affair with Wayne's ex-girlfriend Vanessa Peroncel.
Also pictured was Sam Quek, a member of Team GB's Olympic hockey team, who scooped gold at the Rio 2016 Olympics.
An insider told The Sun: "Sam ticks all the boxes for producers. She's a hugely successful Olympian and is gorgeous to boot. Producers think the personality that has made her a hugely popular member of the GB hockey team will shine through on camera."
Former Strictly Come Dancing pro Ola was also snapped in Brisbane. She's married to fellow dancer James Jordan, who has also appeared in Celebrity Big Brother.
A source told The Sun: "Ola is a no-brainer of a signing. She's well-known, gorgeous and has strong opinions. Having a very vocal husband is an added bonus in the deal. James is not afraid to air his opinions and will make a great guest on the spin-off show while Ola is in camp."
Former Britain's Next Top Model presenter and Capital FM Breakfast Show host Lisa Snowdon kept her head down as she walked through the airport.
A source told Daily Star: "Lisa is a great signing for us. She will certainly look great in a bikini in that jungle shower. She's very much an action girl and she will have plenty of stories to tell.'"
Finally, Diversity star Jordan Banjo was pictured looking cool as a cucumber at Brisbane arrivals hall. He signed off Twitter on 5 November by tweeting: "See you guys soon."
Jordan pretty much confirmed his involvement by telling The Mirror: "I'm really excited to be here but I'm very cared of snakes. I'm petrified of them - snakes, heights and bugs!"
There are far fewer reality shows in this year's I'm A Celebrity lineup, compared to previous years such as 2015 when we had Geordie Shore's Vicky Pattison, TOWIE's Ferne McCann, X Factor's George Shelley and Made In Chelsea's Spencer Matthews?
It had been rumoured earlier this year I'm A Celebrity bosses wanted to reduce the number of reality stars, with a source telling The Sun: "This year [the show] wants to go back to its roots by signing up more cult favourites from the past and current, newsworthy personnel. The last series got a ribbing for having so many reality show stars and giving them lots of camera time."
Ant & Dec return to host this year's main show, while it's all change over on the spinoff programme, which has been renamed I'm A Celebrity: Extra Camp. Joe Swash returns to co-host alongside newcomers Stacey Solomon (his girlfriend!), Vicky Pattison and Chris Ramsey.
I'm A Celebrity starts Sunday, 13 November at 9pm on ITV.
