Justin Bieber arrives at 2012 MuchMusic Video Awards

Justin Bieber has been promoting his brand new scent Girlfriend this week, much to the joy of Beliebers everywhere. The fragrance follows hot in the footsteps of Someday – his first olfactory venture, whose annual sales reached a whopping $39 million in its first year.

'Girlfriend is kind of a more mature version of Someday,' Bieber tells WWD. 'It has some of the same scents to it, but older. It’s going to be a great fragrance, and I think people are going to like it a lot.'

Indeed, on Sunday night, it is rumoured that more than 200 fans camped outside Macy’s in New York to get their hands on the fragrance, which is full to bursting with notes of pear, mandarin, blackberry, jasmine and orange blossom to conjure up the perfect air of 'flirty sophistication' though there is no news of when exactly the scent will launch in Blighty. Come on, Bieber!

Celebrity fragrances are always a hot topic in the beauty industry.  Over the past few years the scent market has been flooded with a vast quantity of olfactory offerings from many of the world’s biggest models, musicians and film stars. The result?  Gentle murmurings by cynical types that there had been a marked turn from quality to quantity with of course lots of money making thrown in for good measure. Whether or not you agree, it’s certainly true that these scents have been bought mainly by fans of the star in question with much lesser appeal to the wider public.

More recently, however, it has seemed that things are set to change in the celebrity scent market and Mark Tranter, Fragrance and beauty buyer at Selfridges agrees. 'Celebrity fragrance is most definitely set for a resurgence – the market seems to have had a thorough clean up and the calibre of the fragrances has been raised significantly,' he explains. 'The new generation of celebrity fragrance seem to have very specific launch strategies, with strong marketing campaigns and a focus on the scent itself rather than just the celebrity.'
