Just hours after winning Celebrity Big Brother on Friday night (6 February), Katie is said to have flown to the European country in an attempt to have corrective surgery on her painful boob.
CBB fans saw Katie unable to lift her arms and visibly in pain due to a botched boob reduction in November.
In the house, Katie told fellow contestant Alicia Douvall that she has a hole from where her breast implant removal surgery had gone wrong.
The mum-of-five also revealed that she was set for surgery that week, but decided to enter the CBB house instead.
She revealed: "They were going to take them out on Monday. That's how bad it's gone under there, it's a hole, my implant was hanging out on New Year's Day.
"But it hasn't stopped me coming in, because I'm not running around."
The former glamour model had a doctor on stand-by while in the house and was seen to be holding her boob in place during the live final.
Horrifyingly, fellow housemate Katie Hopkins - who came second to Katie Price - described Katie's breast as smelling like a "dead hamster".
But it is now believed Katie has left the UK for emergency surgery.
Katie, 36, has returned to where she initially had her reduction, says The Sun.
A source told the paper: "Katie is not well at all and needs immediate medical attention. She has flown out to Belgium so that she can get the help she needs from surgeons."
Pricey bored the tits off me in #CBB. Today, she had her dodgy ones removed by the surgeon. Is that karma?— Katie Hopkins (@KTHopkins) February 7, 2015
Katie H appeared to confirm the news on Saturday (7 February) when she tweeted: "Pricey bored the tits off me in #CBB. Today, she had her dodgy ones removed by the surgeon. Is that karma?"
Katie H has made no secret of the fact she dislikes Katie P, and lashed out at her winning CBB.
Meanwhile, some happier news has also been reported - that Katie and Kieran have invited Keith Chegwin and Cami Li to attend when they renew their wedding vows later this year.
Keith told the Sunday People: "They're getting married again. I've been invited to her vow renewal.
"Kieran is such a loving partner. They seem like such a lovely couple. I can't wait to see her again."
