Britney Spears is ‘disappointed’ that her sister, Jamie Lynn Spears, has quit I’m A Celebrity… Get Me Out Of Here! – but insiders claim the singer ‘isn’t surprised’ by the ‘unprofessional behavior.’

Jamie’s shock departure was announced in a statement on Wednesday, with show bosses revealing the Zoey 101 actress, 32, left the British competition series on ‘medical grounds,’ just days after telling campmates she felt ’emotionally weak.’

But insiders close to Britney, 41, have claimed Jamie Lynn had zero intention of staying on the series for longer than 72 hours – the amount of time required to bank the hefty paycheck for participating.

‘Britney is disappointed, but nothing surprises her anymore when it comes to her family’s unprofessional behavior,’ a source told DailyMail.com exclusively.

‘Jamie Lynn knew damn well going into this that all she had to do was last 72 hours and she was going to get paid. So that is what she did.

‘She never intended on staying any longer than this. This was just a quick paycheck for her – same as the Special Forces was.’

Jamie previously bawled her eyes out on quitting Fox’s Special Forces: World’s Toughest Test after only two days.

At the time, she cited her daughters Maddie, 15, and Ivey, five, as her reason for leaving.

She also had a short-lived stint on Dancing With The Stars after becoming the second celebrity to be eliminated from the current season alongside her partner Alan Bersten, 29.

The source continued: ‘Unlike her sister, Jamie Lynn does not see anything through to the end.’

They appeared to question her reason for leaving the show, claiming she ‘does not have any ailments,’ and added: ‘Using a medical condition surely gets her off the hook without having to explain herself.’

It is not known how much she has been paid.

Jamie was often seen in floods of tears as she pined for her daughters back home in the US during her time on I’m a Celebrity.

During one conversation with her camp mates, she said: ‘I don’t know how I’m so emotionally weak… Why am I crying so much?’

In an attempt to console her, costar Danielle Harold said: ‘Look at the s*** you’ve been through in your life, right? This, a little bit of rain in the jungle, nothing.’

Jamie Lynn replied: ‘But at least all that s*** I could go home to my babies every night, you know? That’s it, that’s all I need in life. It feels a little bit overwhelming. They’re not even close.

‘I’ve got to just do it. I don’t know why I’m being such a baby.’

During Tuesday night’s episode, viewers watched as she broke down in tears again after being offered a small piece of chocolate, before she was comforted by former boxer Tony Bellew, 40.

‘I hate it here so much, I hate it here so much, I hate it here so much,’ she said.

‘I hate it, I hate it, I hate it here. This place is where people go to have the worst days of their lives.

‘Dear God, please help me to make it. I think I’ve got to leave, I think I’ve got to leave.’

Jamie Lynn had talked about Britney during her time on I’m A Celebrity, despite reports that her sister had imposed a strict ban on mentioning her on screen as the pair attempt to rebuild their relationship.

During one conversation with Made In Chelsea’s Sam Thompson, she had revealed that Britney had requested crawfish when she performed her Piece Of Me residency in Vegas between 2013 and 2017.

A show spokesperson for the show said Jamie Lynn was ‘a fantastic campmate who has triumphed at trials and bonded well with her fellow celebrities’

She said: ‘We’re from Louisiana, we love crawfish. My sister and all of us, we love crawfish so much, but she [Britney] only wanted the good crawfish.

‘So the company in Louisiana would have them overnighted in a box for her, in an ice chest… Even in Vegas, she’d have crawfish, [she’d be] eating crawfish in the Elton John suite.’

Louisiana is famed for its crayfish – or crawfish – and popular gatherings include ‘crawfish boils’, which center around eating the crustacean.

Viewers saw Jamie Lynn’s exit on Wednesday night’s episode. It has been confirmed that she will not be replaced.

‘Jamie Lynn Spears has left I’m A Celebrity… Get Me Out Of Here! on medical grounds,’ a statement read.

‘She’s been a fantastic campmate who has triumphed at trials and bonded well with her fellow celebrities.’

Her departure came one day after food critic Grace Dent, 50, quit on medical grounds.
