Singer Beyonce Knowles has had a whiff of the sweet smell of success - $3 million worth of her Beyonce Heat fragrance has been sold since its launch last month.

The perfume hit the US departmental store Macy's in Feburary. Contactmusic.com reports that fans clamoured to purchase the fragrance, which features 'notes of red vanilla orchid, magnolia, neroli and blush peach', and it quickly became America's top-selling beauty counter product.

The fragrance's popularity continues to soar - Macy's CEO Terry Lungren has revealed sales have reached a staggering $3 million in its first few weeks of release.
