JUNGLE QUIT FEARS I’m A Celebrity crew on ‘high alert’ as big name campmate looks ready to quit just hours into series

FEARS grew yesterday that Britney Spears’ sister Jamie Lynn might quit I’m A Celebrity after a tough start.

The actress was said to have been “miserable” in camp following two savage entry trials — a skydive and a critter-filled ordeal called the Temple of Doom.

After struggling through both, Jamie Lynn, 32, isolated herself in camp on Saturday and even stayed in bed yesterday morning, a source told The Sun.

The ITV’s show’s crew have clocked the Zoey 101 star’s behaviour and are now worried she is a “flight risk”.

The source said: “The entry trials for I’m A Celebrity are notoriously tough and Jamie wasn’t the only one who struggled through the challenges.

“But away from the cameras and scenes that aired on TV, it’s her behaviour in camp that has become obvious to crew.

“She has kept herself somewhat separate, not really socialising — and stayed in bed.

“It looked like she is really missing her family and, of course, unlike the other celebs, who are all from the UK and mostly know — or know of — each other, Jamie Lynn didn’t have immediate connections like that.”

Campmates need to stay in the jungle for 72 hours to receive their full pay cheque — a rule that came to light after Gemma Collins’ exit from the show back in 2014.

The then-Towie star revealed she didn’t get her fee in full and ended up donating what she did get to charity.

At the time, her representative said: “I can confirm that the £4,800 fee was the full and final fee that Gemma received for her participation in last year’s I’m A Celebrity.”

Jamie Lynn — the younger sister of Baby One More Time singer Britney, 41 — has form for taking an early cut having quit the US version of SAS: Who Dares Wins two days in.

Leaving the show, called Special Forces: World’s Toughest Test, earlier this year after just 48 hours, Jamie Lynn confided in Mel B, who also took part.

She told the Spice Girls singer: “Like, I just can’t do it one more night. I can’t do it.”

She also said she did not want to be a “crap mum” to daughters Maddie, 15, and five-year-old Ivey.

She added: “I miss my children when I’m away from them for a couple of hours. So this is a very big leap for me. Not only do I love them and want to be with them, but being away from them like this, even if it’s something for myself, makes me feel like a crap mum.

“They didn’t ask for their mom to be gone. My babies.”

More recently, Jamie Lynn had a quick exit from Dancing With The Stars — the US version of Strictly Come Dancing — when she was voted out in week two.

During entry interviews for I’m A Celeb, Jamie Lynn — who has featured in recent Netflix hit Sweet Magnolias — hinted that the strikes by American actors’ union Sag-Aftra left her considering work she would not usually take on.

She said: “I think it is so far out of my comfort zone and this year with Sag being on strike, I have said ‘yes’ to a lot of unscripted projects.”

But she added: “I am really enjoying throwing myself into these experiences.

“When they approached me, the first thing I had to do was talk it over with my family and my kids to make sure they were OK about me being gone for this amount of time.

“Once I got the all-clear from everybody, I was like, ‘Yeah, let’s go’.”

In last night’s amazing opening episode, viewers saw Jamie Lynn take part in a skydive alongside Hollyoaks star Nick Pickard, 48, and JLS singer Marvin Humes, 38.

Grimacing at the task, Jamie quipped: “What’s the worst that could happen? Just kidding, a lot of really bad things could happen.”

Later in camp, Jamie Lynn said after meeting her fellow contestants: “Everyone so far has made a wonderful impression on me. I’m the only American here.

“Everyone’s been really kind and really nice. I’m really impressed. Maybe I’m being really naive.”
