Katie Price has reportedly flown to Brussels for emergency surgery.
The former glamour model has been suffering ongoing problems with her left breast since having a botched boob job, which left her with an infection and a hole in her breast, and is now said to have travelled abroad to have it fixed.
A source told The Sun newspaper: "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."
The 36-year-old star - who has son Harvey, 12, from a previous relationship and 17-month-old son Jett and five-month-old daughter Bunny with current husband Kieran Hayler - has delayed going under the knife to take part in British reality show 'Celebrity Big Brother', on which she was crowned winner on Friday.
However, the brunette beauty - who was seen clutching her boob as she exited the reality show house - has now jetted off to undergo an urgent operation.
Meanwhile, Katie is said to have discussed her plans to reunite with ex-husband Peter Andre - with whom she has nine-year-old son Junior and seven-year-old daughter Princess - during her time on the show.
Her housemate Kavana revealed: "Katie did speak about Peter. She says it like it is.
"She would like some kind of reunion for them to speak ... I think she is on the side of having some kind of chat with him about stuff."
However, Peter - who welcomed his third child, Amelia, with girlfriend Emily MacDonagh last year - doesn't appear to be interested in reconciling with the star.
Kav added: "I think it's him that doesn't want it, according to her."
