Mutya Buena has been declared bankrupt.

The MKS singer was given the order by a High Court Judge earlier this week due to a reported unpaid tax bill, but her representatives told The Sun newspaper she is blaming the bankruptcy on an ''administrative error''.

According to paperwork lodged with Companies House, the 29-year-old star owed her company God Made Me Funky around £22,500 and the organisation only managed to register a profit of £902 in March 2013.

What's more, her company Sacred Three Limited is reportedly £10,000 in debt.

MKS - who are completed by her fellow former Sugababes founding members Siobhan Donaghy and Keisha Buchanan - haven't released any material since September but Mutya's representatives insists she ''continues to write and record with the band''.

Following their comeback, the group - also known as Mutya, Keisha, Siobhan - released single 'Flatline' but it only made number 50 in the UK chart.

However, Mutya is not the only singer popular in the early 2000s who has recently been made bankrupt.

Just last month, Blue singer Antony Costa declared himself bankrupt, following in the footsteps of his fellow bandmates Duncan James and Simon Webbe who both declared themselves bankrupt last year after they were unable to pay their debts.

Atomic Kitten singer Kerry Katona - the previous face of payday loan company Cash Lady - has been declared bankrupt twice, in 2008 and last year, and as a result she asked for money from her wedding guests at her nuptials to George Kay earlier this month to help feed her children.

Kerry - who has kids Molly, 13, Lilly Sue, 11, Heidi, seven, and Max, six, from previous relationships and five-month-old Dylan-George with George - said: ''I have asked for money. Just a fiver in a card will do. I'm bankrupt and I've got five kids to feed.''

Several other stars including S Club 7 pair Jo O'Meara and Paul Cattermole, who are set to make a comeback with the band, have also both faced bankruptcy, as has Westlife's Shane Filan.
