Kerry Katona is in hospital after she showed signs of the potentially fatal condition pre-eclampsia, her spokesman Max Clifford said.

The 27-year-old former winner of I’m A Celebrity… left rehab just days ago and is now being treated in Macclesfield, Cheshire, Clifford said.

Katona, who plans to name her unborn baby boy Maxwell after the full first name of the PR guru, is there as a ‘precautionary measure’, he confirmed.

“She’s been in a lot of pain, particularly in the last few days,” he said.

“The symptoms she’s showing are possibly that of pre-eclampsia.”

He said Katona, a former member of the girl band Atomic Kitten, had been troubled by swollen feet and legs and pains going up her feet.

“It could be water retention,” Clifford said. “She’s still in hospital at the moment.

“She has been in increasing pain. She can hardly walk.”

The troubled star has two daughters with her first husband, former Westlife singer Brian McFadden, and a third daughter with her second husband, Mark Croft.

Her first son is due in May and Clifford said having the baby named after him would be ‘lovely’.
