Kerry Katona does the flirty on Mark

LIPOSUCTIONED star Kerry Katona is having a marriage wobble-after husband Mark Croft caught her secretly flirting with men on the internet.

The pair had a blazing row when he discovered Kerry had sent sexy messages to a string of new male pals, the News of the World can reveal.

Kerry is recovering after going under the knife to shrink her 34GG bust to a DD and suck out TWO LITRES of fat from her tum, bum and thighs.

According to pals, her trimmer shape has boosted her confidence and she's been chatting to fellas in online forums and on Facebook.

Sexy

One friend said: "Kerry's got some confidence back. It's been an ego boost for her to be considered sexy again.

"Mark caught her out and went mad about it. He's the one who is usually the player and he doesn't like it."

But even though she's slimmed down, the skint mum-of-four can't be bothered to maintain her new figure.

Instead, she's propped up in bed at her £1.3million Cheshire mansion chain-smoking, and scoffing curries and sausages and chips, washed down with fizzy pop.

Kids Molly, seven, and Lilly-Sue, five, have been packed off to ex-hubby Brian McFadden parents in Ireland, and tots Heidi, 18 months, and four-month-old Maxwell-are with family friends. The pal added: "Kerry's been whingeing about getting back in shape, but she's not taking very good care of herself.

"You'd think she'd be tucking into salad and drinking water but she's straight back on her old diet of junk food and fags. Her attitude is she can eat what she wants because she can get the fat sucked out again."

Kerry had the eight-hour op- DOUBLE the time it should have taken-nearly a fortnight ago. The pal went on: "She loves a drama, especially the fact it took so long to get her in shape, but Mark has been ribbing her saying it was because she had so much flab to get rid of."

Kerry-who turned 28 yesterday- was made bankrupt last month over an unpaid £82,000 tax bill. But MTV paid for her recent surgery and filmed it for her show.

We can also reveal that the Inland Revenue has FROZEN her bank accounts-and the couple are surviving on 38-year-old Mark's £19,000 savings. The source added: "Kerry keeps saying she is waiting for cheques to clear but they are in a total mess.

"Her cash flow has got out of control since she met Mark."
