Kerry Katona has plunged her troubled marriage into even deeper crisis by sharing a hot tub with a hunky Royal Marine.

Husband Mark Croft was furious when he found the 29-year-old bikini-clad reality star and married Scott Partis climbing out of the spa bath.

Wine-fuelled Kerry – at an exclusive £1,650-a-week fitness centre to shed weight – was hastily pulling on a bathrobe as Scott, 26, emerged in just his trunks.

Mark arrived on the fourth day of her stay and the couple spent an uneasy night together before they smiled their way through a lucrative magazine shoot next day.

But only days later Mark exploded during an argument over money and accused his wife of having an affair with Scott, who works as a fitness trainer when he is on leave.

Ex-cabbie Mark, 39, discovered cocaine-snorting Kerry had been sending Scott and a fellow Marine emails urging them to meet up with her again.

Mark screamed: “Have you had an affair with that Marine? Is that why you haven’t been answering your phone and replying to my texts?” Mum-of-four Kerry insisted: “Nothing happened. I didn’t answer my phone because I was out training. There’s nothing going on.”

The hot tub incident came as shamed Kerry spent a week at Carrington House, a “boutique boot camp” near the beach at Hunstanton, Norfolk.

The I’m A Celebrity star has already admitted taking drugs every day of her stay even though she insisted she was at the Georgian Grade II listed fitness centre to trim her size 16 shape.

Booze
Kerry confessed: “We were doing it every night, off our heads.”

A source close to the former Atomic Kitten singer said: “Kerry was taking drugs in her room out of sight of the owners. Drug taking and drinking are not tolerated. But Kerry did manage to lose 6lbs in just four days.

“Both Marines are entirely professional but Kerry was craving their attention all the time.

“One of them was relaxing in the hot tub alone when Kerry wandered in. Kerry had been drinking white wine she bought from a local shop.

“No husband would be happy to arrive and find his wife off her head and pulling on a dressing gown.

“Mark didn’t see Kerry in the hot tub with the Marine but was shocked to find her walking towards him with the gown wrapped around her bikini. It was obvious she had been drinking for hours.

“Mark managed to keep a lid on things but by late evening Kerry couldn’t take any more booze. She went to bed alone, leaving Mark chatting.

“Next day Kerry and Mark had to pose for photos and pretend to be getting on. He had been wondering what she was up to as he had been texting her and calling her all week and had hardly been able to get hold of her.

“He just wanted to know what was going on while he was helping look after the children back home.”

The showdown came two weeks after Mark was pictured groping lap dancer Claire Bassett in the Majorcan resort of Magaluf. He was caught out after downing vodka and Red Bull and sambuca shots at a pal’s bar.

Mark and Kerry patched things up after he insisted he did not have sex with Claire.

But the couple, who have a £1.3million home in Wilmslow, Cheshire, have also had fierce rows over the state of Kerry’s finances.

She was arrested for allegedly assaulting accountant David McHugh, a pal of Mark.

Kerry was bailed until October and faced a separate police quiz after a video emerged apparently showing her snorting cocaine in the bathroom at her home.

Friends fear Kerry is heading for total meltdown. The star, made bankrupt over a tax bill, has lost her contract as the face of Iceland stores.

And MTV bosses pulled the plug on her reality show Kerry Katona: What’s The Problem amid falling ratings earlier this year. She and Mark have split three times this year and in July Mark was said to have asked Kerry for a divorce. Kerry said last month: “I’ve lost almost all control over my life and all the money I earned in the past year.

“I’m now working flat out just to pay off this huge debt – but I have to do it for the kids.” She wed Mark on Valentine’s Day 2007 and they are parents to Heidi, two, and 10-month-old Max.

Kerry also has Molly, seven, and Lilly-Sue, six, by her ex, Westlife singer Brian McFadden. She faces a costly legal battle if Australia-based McFadden, 29, decides to seek custody of their children.

Carrington House has a high reputation as a health and fitness centre.

Its wood-panelled hot tub is in a converted barn behind the main hotel.

The camp’s website says: “Our staff of top serving and ex-military physical training instructors know how to make your mind and body work as a team.

“They will show you how to keep to your health and fitness goals even when you really don’t feel like it.”

Marine Scott, who lives with his wife Beverley, 31, in Hull, East Yorks, told a friend: “When Mark Croft came in I was the only one in the hot tub. Nothing went on.”

Carrington House would not comment on Kerry last night. But a source said: “We expect all guests to abide by our rules.”
