See Kerry Katona's transformation over the years...

Kerry Katona is born on 6 September 1980.

The pretty teenager poses for a school picture in 1995. She’s been to 8 schools by the time she’s 11.

Kerry – whose suicidal mum Sue has drug and alcohol problems – is taken into care several times as a child.

After working as a nightclub lapdancer and glamour model, at 18 Kerry joins Atomic Kitten.

The group hit the big time in 2000 but after falling pregnant with her and boyfriend Brian McFadden’s first baby, Kerry Katona leaves the band the following year.

Her daughter Molly is born in August 2001 and she marries Brian in January 2002.

A year after welcoming her second baby, Kerry Katona is on a high when she wins I’m A Celebrity in 2004.

But the star – whose second girl is called Lilly-Sue – is hit hard when she splits from Brian later that year.

She becomes a ‘cokehead’ and ends up in rehab. She’s diagnosed with bipolar disorder during counselling and put on medication.

Kerry hooks up with teenage sweetheart Dave Cunningham before showing off her new man and ‘soul mate’ for the first time, taxi driver Mark Croft.

Six days before welcoming her third baby, Kerry Katona marries Mark on Valentine’s Day 2007.

They name their daughter Heidi and have son Max in 2008.

But Kerry’s troubles continue when she’s cautioned for possession of a controlled substance in September 2009.

A month later, she learns that she won’t face prosecution following her arrest on suspicion of assaulting her accountant.

She finally splits from Mark in March 2010, later telling Now: ‘My days with Mark were the darkest days. It’s like a big grey cloud.’

Kerry seems to get her life back on track with appearances on Celebrity Big Brother and Dancing On Ice and rejoins Atomic Kitten for The Big Reunion in 2013.

In 2014, she and ex-bodyguard welcome daughter Dylan-Jorge.
