Gillian McKeith returned on 'I'm A Celebrity... South Africa' as a surprise late arrival.
The 63-year-old TV nutritionist - who famously fainted during the Bushtucker Trials when she first appeared on 'I'm A Celebrity... Get Me Out Of Here!' - has made a comeback 13 years later to join the likes of Carol Vorderman and Helen Flanagan in an all-star version of the ITV reality show.
Hosts Ant and Dec revealed the huge twist at the end of the opening episode of the spin-off - which is set in a new camp in Kruger National Park - as a large box was brought in on Monday night (24.04.23).
The contestants opened the box, and Gillian - who appeared on the 10th series in 2010 - leaped out.
She quipped: "I couldn't let you do this without Jungle Gill."
Her appearance could cause some friction in the camp, given the way she and musician Shaun Ryder clashed on a number of occasions in 2010, with the Happy Mondays singer referring to her as "a f****** irritating woman" at one point.
In a preview for tonight's episode, Shaun insists that Gillian "should have stayed in the box".
Meanwhile, the 'You Are What You Eat' star has admitted she is even more "apprehensive and petrified" this time but that's what is inspiring her.
She said: "Now when I think about doing 'I’m A Celebrity' again, I feel apprehensive and petrified.
"It’s going to be more terrifying this time because, back then, I didn’t know what to expect, but this time I can’t use that as an excuse.
"What I felt before feels 1000 times worse now and all of it freaks me out, but I feel I’ve got a calling to represent all the scaredy cats in Britain – and that is the reason why I’ve said yes."
