The former Atomic Kitten, who is seven months pregnant, married the cab driver at Gretna Green on Valentine’s Day.

Her divorce from Westlife star Brian McFadden was finalised last year.

Kerry, 26, told OK! magazine: "I’m so scared this time because my divorce has just come through and I keep thinking, ’Is this too quick?’ Or, ’Is he going to leave me?’ I want it to work so badly and I don’t want it to end.

"I hope to God this lasts, another divorce would kill me."

OK! bought the rights to the low-key wedding. It reported Kerry was "riddled with pre-wedding jitters", beset by loneliness and miserable that she had no friends to attend the ceremony.

As the evening wore on, the couple had a quarrel and Kerry demanded Mark sleep in a separate bedroom.

But Mark came down in the morning and told guests: "We’re fine, it was just a few hormones."

The 35-year-old cabbie proposed to I’m A Celebrity winner Katona three weeks after they met last year.

He told the magazine he was looking forward to getting married because "she’ll legally be my bitch".

And he recalled: "I said to her once, ’There’s a pair of pants in the bedroom for you, try them on’. She came out saying they didn’t fit so I said, ’Exactly, I wear the trousers’."

Kerry and Mark tie the knot - Feb 15 2007
Kerry Katona has married her boyfriend Mark Croft in a ceremony at a private chapel near Gretna Green.

The 26-year-old, who is expecting a baby girl at the beginning of April, is currently at home relaxing after the ceremony.

The couple also plan to hold another ceremony and a blessing later this year, and they have also postponed their honeymoon until later this year.

Kerry, who has two daughters from her relationship with former Westlife singer Brian McFadden, began dating 35-year-old Mark in February 2005 - getting engaged just five weeks later.

The loved-up couple had only invited two friends and Mark’s mother to watch them exchange vows at the Forge Chapel at the Mill Hotel, according to The Sun.

"There were security guys with earpieces shielding Kerry with umbrellas," a source told the paper. "You’d have thought they were guarding the Queen."

The union was in stark contrast to Kerry’s first wedding to Westlife singer Brian McFadden in January 2002.

The couple married in County Meath in Ireland with a reception for 200 guests held at nearby Slane Castle, reportedly costing £400,000.

Kerry arrives in Gretna for wedding - Feb 14 2007
Kerry Katona’s fiance gave guests the thumbs up ahead of a low-key wedding ceremony in Gretna Green.

Cab driver Mark Croft arrived at the Mill Hotel for his wedding tonight to the former Atomic Kitten singer, who is almost eight months pregnant.

Bouncers held up umbrellas to stop the waiting paparazzi catching a glimpse of the couple, after a blacked-out Mercedes people-carrier followed by two Mercedes cars arrived at the three-star hotel in Dumfries and Galloway.

But 35-year-old Mark was later spotted gesturing with his thumb up to another of the guests.

The couple’s wedding banns have been posted at Gretna’s registration office for the past fortnight.

Today’s union is in stark contrast to Kerry’s first wedding to Westlife singer Brian McFadden in January 2002.

The couple married in County Meath in Ireland with a reception for 200 guests held at nearby Slane Castle, reputedly costing £400,000.

The 26-year-old is now expecting a baby girl after the couple got together in January last year, getting engaged just five weeks later.
