But they aren't the only ones heading into the Australian bush this weekend - 2008 winner Joe Swash and Laura Whitmore will be back to present ITV2 companion show Get Me Out of Here Now!, this time bringing along hot new comedian Rob Beckett for the ride.
Speaking to Digital Spy ahead of the new series, the trio shared tales of 'stinky' former stars, warned us about deadly Australian drop bears, and named Boris Johnson as their dream celebrity campmate....
It's not long now until you guys will be out in Australia again for Get Me Out of Here Now. How are you all feeling, excited?
Rob: "Yeah, I can't wait. It's my first time so I don't really know what to expect."
Laura: "I'm looking forward to it because last year was my first time, so I was going through what Rob's going through. I'm a little bit more laid back, a little bit more okay because I know what to expect. And then the old one over here is okay, no bother... Gramps in the corner there."
Joe: "I can't wait to go out there, can't wait."
So Joe and Laura, have you been giving Rob tips?
Laura: "Yeah, Joe has been giving really good tips, haven't you? Just making up animals that don't exist to be aware of."
Rob: "Yeah, and how you said you have to be careful of drop bears, which are mental koala bears that climb down trees and chase you."
Joe: "When I went to Australia first time [to compete], I was told all these horror stories about these crazy animals. I was really freaking out about them. And it took three years for them to say 'No Joe that was a joke we told you in the first year'. So yeah, I had to pass it along."
Rob, are you going to be doing stand-up routines like Russell Kane did before you?
Laura: "You're going to dye your hair like Russell, aren't you?
Rob: "I'm sort of taking over his role of resident stand-up comedian. It'll be slightly different - I've got a different style to Russell anyway. I'm good friends with him and I do his tour support as well. I had to [say] 'I'm pulling out of your whole tour because I'm doing your old job. That okay? We still cool?' But he was so happy for me. Well, it would have been awkward if they'd chucked him out, but he wanted to go."
Who would you love to see on I'm a Celebrity?
Laura: "Grace Jones. That would be amazing. Just some good characters that cause a bit of controversy."
Rob: "Boris Johnson. It would be amazing if he was just really sort of articulate and clever, and the buffoon thing was a massive act."
Laura and Rob, would you be tempted to follow in Joe's footsteps and go into the jungle?
Laura: "I couldn't. I physically couldn't. I'm such a girl. Like even when we stay in this amazing apartment [for Get Me Out of Here Now!] and there's a little spider I'm like, 'Oh my God'. When I watched the show at home I always assumed they get slipped a burger at night, but they're starving. So because I've seen that, I'm just like, 'No way!'"
Rob: "I don't think I could, just for the fact of not eating. I think I'd kill someone."
Joe, would you go back if the much-rumoured 'Ultimate' series ever happens?
Joe: "I'd consider it, but I don't think that this show needs [an 'Ultimate' edition]. When you do a 'best of the best' it kind of puts the sell-by date on, like [with] Big Brother. But I think I'm a Celebrity has longevity. I don't think you need it."
Rob: "I think people are always going to enjoy seeing celebrities out of their comfort zone. Big Brother, it's good, but they're not really pushed and stretched like they are on I'm a Celebrity, so you never really see people being their true selves."
So, would you say that I'm a Celebrity, unlike most other reality shows, doesn't really struggle to stay fresh?
Joe: "I think the only problem that it faces is getting celebs to do it. It's 10 years old now, but every year it feels fresh."
Laura: "I think it's getting better. I mean the trials are getting bigger, better... there's so much more to do. I think there's many years left. I know with other shows there's talk of, 'Is it going to stay?', but no-one's ever talked like that for I'm a Celeb."
It was reported that Celebrity Big Brother banned TOWIE contestants from the latest series - is I'm a Celebrity open to anyone?
Joe: "I wouldn't say no, whoever you are. I mean once you start shutting the doors to certain people you become a little judgemental."
Laura: "I would have said Mark Wright from watching TOWIE was going to be real sleazy and horrible, and then [on the show] he's lovely and not like that TOWIE character at all. But I remember seeing Stephanie Powers and being like, 'Oh my god from Hart to Hart, she's amazing, she's a really big character', and then she was a bit boring in there."
Rob: Yeah, it's not for TV shows to decide who's a celebrity is it, it's for the public."
So which past contestants have surprised you the most?
Laura: "Mark, completely. Because beforehand I was like, 'Urgh'."
Rob: "I thought that was one of the biggest image shifts, because he's just the nicest man."
Joe: "I think Stacy Solomon [changed the opinions of] so many people. I just thought she was going to annoy the s**t out of me. But she was really nice. She really changed my view in there. I thought all that [persona] was put on, but she was amazing. She stood up for what she believed in."
What would be your worst fear at a Bushtucker Trial?
Laura: "Anything with bugs. Or eating... it would be eating stuff."
Rob: "See, I'd rather do that [than] having a helmet on when they pour stuff in. [Nothing] that's going in an ear or nose. I'd rather eat anything. I've set myself up there, haven't I?"
Joe, when you see the Bushtucker Trials and the celebs in camp, do you feel nostalgic?
Joe: "Yeah. I mean the first year I went back [for Get Me Out of Here Now!] I was really jealous that I wasn't in there doing it, but I love doing ITV2 stuff. I get the best of both worlds. I get to see camp and be around to experience it, but when we go home I can have a good bit of egg and bacon, a nice shower."
Do the celebs not get spruced up when they come to see you after leaving the jungle?
Joe: "No they stink. I got quite close to Stacey, like I gave her a good cuddle, which I won't be doing this year to the winner. I was hum-dinging by the time I got out of there. Everyone was stinky, so no-one knew if it was coming from them. But yeah, they do stink when they come out of there."
I'm a Celebrity...Get Me Out of Here! begins Sunday (November 11) at 9pm on ITV1. The first edition of Get Me Out of Here Now! follows immediately afterwards at 10.35pm on ITV2
