And they are…Lisa Curry and Steve Price.
Curry, a three-time Olympian, will be the first celebrity heading into the jungle when the reality TV show kicks off tonight.
Curry told The Daily Telegraph that viewers could expect to see a more vulnerable side to her.
“I would say that I’m scared of spiders and snakes, I can’t stand them. I really don’t like heights and I don’t like pretentious people. It might be the wrong show," she added.
Listen to The Binge hosts Laura Brodnik and Tiffany Dunk explain who is going into the jungle on I'm A Celebrity Get Me Out Of Here.
Promotional videos for the show have teased that viewers can look forward to seeing a US sitcom star, a radio shock jock, a top model, an Olympian, a singer and an AFL player in the depths of the South African jungle.
The 54-year-old former Olympic swimming champion has won 15 gold, seven silver and eight bronze international swimming medals, and is the only Australian swimmer to have held Commonwealth and Australian records in every stroke except backstroke.
Curry's also no stranger to reality TV - she appeared on Nine's Celebrity Apprentice Australia in 2011.
“I have to be careful because I am quite opinionated and I certainly won’t put up with anyone who is being mean to someone," she told the Daily Telegraph.
Having split from her ex-husband, fellow Olympian Grant Kenny in 2009, Curry is now engaged to Elvis impersonator, Mark Andrew Tabone.
Curry will be joined in the jungle by 2BG shock-jock Steve Price.
The 62-year-old, an outspoken regular panelist on Channel Ten's The Project, told the Sydney Morning Herald that he is "ready for Australians to see a softer side of him".
"I think doing the job that I do, particularly radio but also on The Project, it's dependent on having interesting things to talk about. If you lead a boring, protected life, you don't have as much to talk about," he said.
"Clearly, the producers of the program are going to put people in that create some sort of conflict, but I don't have to apologise for or explain my views," he says. "I don't want to bore everyone at 7.30 at night by giving a political lesson, though. The different side they'll see of me is that I want to talk about more interesting things than politics," he added.
Price also hinted that his particular skillset of getting "people to tell me things about them" would come in handy in jungle. But he's also admitted he's not going to like "not being in control".
"I'm going to be wanting to be in charge but there will be other personalities within this group who won't want me to be in charge. They'll want me to just be one of the group. That's going to be a difficult thing for me because I like to run things."
On last week's episode of The Binge, Laura Brodnik suggested that Curry may have been heading into the jungle, after getting wind of a rumoured visa approval.
"Apparently Olympic swimmer Lisa Curry has applied for a South African visa and has been approved," she said.
We can't wait to see who else will be heading into the jungle tonight.
There's so much new TV you have to know about, and The Binge is here to catch you up.
