Former I’m A Celeb winners Vicky Pattison, Charlie Brooks and Joey Essex have made their way to Wales in order to isolate ahead of a potential surprise appearance on I’m A Celeb 2020. Apparently, even the stars themselves don’t know what producers have planned for them yet–with the possibilities including presenting special trials or even spending time in camp.A source who spoke to The Sun said: ITV producers love having a trick or two up their sleeve.What better way to celebrate 20 series of the show than getting some of the stars of yesteryear to take part in some way? As always with the jungle, they’re keeping their cards close to their chest and have yet to decide exactly what they will do with Charlie, Vicky and Joey, but it could be any number of things.I’m A Celeb 2020 surprise campmates?It wouldn’t be totally unprecedented for Vicky, Joey or Charlie to make a late entry to the show as I’m A Celeb 2020 surprise campmates. Previously, the only celebrity to have gone on I’m A Celebrity… Get Me Out Of Here! as a campmate twice was Katie Price, who appeared on the show in 2004 and 2009.However, with performers Ruthie Henshall and Russell Watson already expected to be heading onto the show as late entry campmates, we reckon it’s more likely that Vicky, Joey and Charlie will be taking on some kind of presenting role on I’m A Celeb 2020. Then again, this is 2020, so anything could happen!The Daily DropOne possibility is that Charlie, Vicky and Joey will feature on brand new I’m A Celeb spin-off show, The Daily Drop, which is set to be presented by Vick Hope. Following the cancellation of long-running spin-off show Extra Camp, the Daily Drop will be available to watch on ITV Hub from 7am each morning.
