But now she has real competition, appealing to exactly the same market. Because former husband Peter Andre has decided to launch his own scent. And unusually Pete is going directly up against his ex with a fragrance for women, rather than men.
According to The Perfume Shop, which has secured exclusive rights to sell Pete’s first ever fragrance until Christmas, it’s a guaranteed hit.
"There has already been an overwhelming demand for the fragrance via our website and switchboard ahead of the launch. It may well be the biggest seller of 2009," says head of sales Cathy Cornmell.
The fragrance has been named after one of the tracks, Unconditional, on Pete’s album and is a floral-musk eau de toilette which the singer calls "classical and sexy at the same time".
It has a top note of soft apricot, a heart of jasmine, patchouli and rose and a base of vanilla, musk and amber. "I’m so proud of this fragrance," says the Aussie star.
Unconditional goes on sale October 29 across all 177 The Perfume Shop stores, with prices starting at £14.99 for 30ml; call 0845 601 1950 for your nearest or visit www.theperfumeshop.com.
