Cheryl Cole's success on The X Factor has helped chart act Girls Aloud to amass a fortune of £30 million, new figures reveal.
Cole's wealth - thanks to her ad deals, X Factor judging and successful solo career - has rocketed by 150% in the past year to £10 million.
And figures to be published in the latest Sunday Times Rich List this weekend show her bandmates Nadine Coyle, Sarah Harding, Nicola Roberts and Kimberley Walsh each have around £5 million thanks to their string of hits.
Cole is ranked number four in the rich list for music millionaires under 30, jointly with singer Katie Melua.
The number one slot is jointly held by Leona Lewis, Charlotte Church and last year's top young music earner Katherine Jenkins.
They are each on £11 million with Lewis moving up from last year's number six with a 38% rise in wealth. Jenkins went up £2 million (22%) while Church remained steady.
Two of those with the biggest fortunes last year's list violinist Vanessa Mae and Coldplay star Will Champion are too old to qualify this year. Mae is worth £30 million and Champion £32 million.
The 22nd annual Sunday Times Rich List is published on Sunday profiling the wealthiest people in the UK and Ireland.
