Danny Baker and Martin Roberts enter camp in I'm A Celebrity
Broadcaster Danny Baker and TV presenter Martin Roberts brought the threat of a storm to the peaceful I'm A Celebrity ... Get Me Out Of Here! camp tonight when they became the programme's two newest contestants.
The ITV show has been uncharacteristically harmonious so far this year with all of the celebrity campers getting on well but the addition of BBC Radio 5 Live presenter Baker and Homes Under The Hammer host Roberts could spell the end of happy days in the jungle.
Baker and Roberts arrived just as the episode was ending, leaving viewers to wait until Friday evening to see if they stir things up for the contestants, and the new additions were immediately pitted against each other for the next Bushtucker Trial.
They were asked to choose a partner to do the challenge with them, with Baker picking mathematician Carol Vorderman and Roberts opting for Olympic hockey player Sam Quek.
This will be one of Baker's final TV appearances as he has announced he will retire from the airwaves once he turns 60.
Speaking before entering the competition, he said: "I have been doing telly for 40 years, I'm 60 next year and I've got no ambition to be on telly any more.
"The only show I've ever wanted to do is this. It's like being asked to do a West End musical."
He added: "This is, in modern TV, as good as it gets - they fly you around the world, put you in a hotel with a beach, then you play games in the jungle."
Baker, who underwent treatment for throat and mouth cancer after being diagnosed in 2010, said: "When this came around, rather than disappearing quietly, I thought 'why not do one last big television programme?'
"I just don't want to do any more telly or radio or anything else after June, when I'm 60."
Earlier in Thursday's episode, f ormer EastEnders actor Larry Lamb spoke of his real-life heartache over not knowing whether he has any grandchildren.
The 69-year-old is a father-of-four but he has only seen his eldest daughter Vanessa, born in 1969, once, when she was seven months old.
Emmerdale star Adam Thomas began asking him about his TV presenter son George Lamb, 36, and then pressed him on whether he had any grandchildren.
Lamb said: "I might have, I don't know - I've got a daughter you know, a long-lost daughter, so I might be."
When Thomas asked if he wanted to find out, he said: "Yeah, I always did, I always have, but the point is that me and her mum broke up before she was born and then she was adopted by her mum's new husband, so I never had anything to do with her and you can't just go bouncing back into someone's life, you know."
On whether she still lives in the UK, Lamb said: "I've no idea at all where they are but I think about it a lot."
The actor had daughter Vanessa with his first wife Anita Wisbey, then son George with second wife Linda Martin, and also has two more daughters, Eloise and Eva-Mathilde, with current partner Clare Burt.
In 2011 he told MailOnline: "Vanessa's mother Anita remarried when Vanessa was three, so I wasn't included in the raising of the child because she had a stepdad - I don't even know whether she knows I'm her biological father.
"I don't know if Vanessa and I will meet up some day - it feels so difficult because it's not for me to go delving into her life.
"The thought that she might have already made me a grandfather has often crossed my mind."
At the beginning of the episode, Lamb impressed the younger campers with his exercise regime of squats and push-ups as ex- footballer Wayne Bridge said: "If I'm in that shape when I'm his age, I'll be absolutely buzzing."
Gogglebox star Scarlett Moffatt was not quite so impressed with his tips on how to use the toilet perfectly as he dished out instructions on how to sit and where to place your feet.
She said: "Larry is the expert in everything, from politics to pooing, Larry knows it all.
"I've been pooing for 26 years of my life and all this time I thought I was doing it right, who would have thought I'd come to the jungle and learn how to have a crap."
I'm A Celebrity... Get Me Out Of Here! continues on ITV at 9pm.
