As reported in the NME, Adele is at number nine with an estimated £6m fortune (she's tied with Lily Allen, Taio Cruz and Amy Winehouse), while Florence is at number fourteen with £5m.
Cheryl Cole (who The Telegraph refer to as "the former Girls Aloud member") is tied with Leona Lewis at number two with £12 million. The rest of Girls Aloud each have half of that amount.
Number one, of course, is Katherine Jenkins. JENKOOOOOO.
