'5, 6, 7, 8' hitmakers Steps are leading the way in fragrance sales after releasing their perfume 'Guilty Pleasure' earlier this week.

It hit shelves at The Fragrance Shop on Monday, November 12 and despite being packaged as a mirrored disco-ball, 'Guilty Pleasure' has shifted enough units to beat the likes of Britney Spears, Lady Gaga and Madonna in sales and is now the store's No.1 selling scent.

The perfume has been described as "a dazzling fruity floral fragrance designed for fun loving women" and Daniel Thompson, spokesman for The Fragrance Shop, explained that it wasn't expected to do so well commercially:

"Celebrity fragrances are certainly on the up in the fragrance world with more people turning to celebrity scents that ever before. The latest launch from Steps has seen them shoot to the top of the celebrity fragrance chart beating Britney, Lady Gaga and Madonna."

"The disco ball bottle, fun floral scent and long awaited return reunion for fans proved too much of a temptation for their guilty pleasure."
