When asked by a British magazine what she and George had put on their present list, Kerry replied: "No, I have asked for money. Just a fiver in a card will do. I'm bankrupt and I've got five kids to feed."
Atomic Kitten singer Kerry was first declared bankrupt in 2008, after she failed to pay a tax bill. Earlier this year there were reports she was filing for the third time, but she denied the claims.

But Kerry clearly wasn't going to let her money problems ruin her big day, and the only thing on her mind was marrying her 'soul mate'.
She continued: "The firs time [I was married] I was an absolute baby. The second time I didn't know if I was coming or going. I was all over the place. I have grown up a lot. I was single for four years. Now I have met my soul mate."
In 2002 Kerry married former Westlife star Brian McFadden. They separated in 2004, and their divorce was finalised in 2006. Together they had two daughters, Molly and Lily-Sue.

She and taxi driver Mark Croft married in 2007. They also had two children together, Heidi and Max.
Kerry and George, who are parents to daughter Dylan-Jorge, didn't quite have the smooth wedding day they were hoping for. According to reports, Katie Price quit her bridesmaid duties on the day because her dress didn't fit.
