BRITNEY Spears is said to be "disappointed" but "not surprised" that her sister Jamie Lynn quit I'm A Celebrity, according to reports.
Insiders have claimed that Britney has branded her behaviour as "unprofessional" but said she 'wasn't surprised'.
It was confirmed by I'm A Celebrity bosses on Wednesday that Jamie Lynn had walked out of the jungle on medical grounds.
But a source told Mail Online: "Britney is disappointed, but nothing surprises her anymore when it comes to her family's unprofessional behaviour.
"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."

The Sun previously told how Jamie Lynn will receive her full agreed fee for taking part in I'm A Celebrity.
Campmates were seen being told in Wednesday night's show that Jamie Lynn, 32, had left the jungle and would not be returning.
The gang appeared surprised, despite the Zoey 101 star having cried on and off for days about missing home and her children.
Her exit came two days after Grace Dent quit I'm A Celebrity.
The food critic also left on medical grounds and is already back in the UK after packing her bags and heading home.
Britney, meanwhile, never spoke publicly in support of her younger sister during her time on the ITV1 show.
However, she did share several cryptic messages on Instagram that suggested to her millions of fans that she was tuning in.
Britney's posts came as Jamie Lynn opened up about their family feuds saying they just fight more than most.
First, the 41-year-old popstar posted a short clip from the Disney film, The Aristocats.
The character of Marie (played by Liz English) was arguing with Berlioz (played by Dean Clark).

The grey-haired male cat exclaimed: "Well, she started it."
But the white-haired kitty retorted: "Ladies do not start fights, but they can finish them."
In another seemingly veiled dig at her younger sibling, she captioned the post: "I never start fights but I can end them all ???? !!!"
Jamie lasted 10 days in the jungle before she quit.
She has since broken her silence on social media and said she "can't wait to share with y'all everything about this once in a lifetime experience".
However, she has not confirmed when exactly that will be.
