The Perfume Shop has announced that it sold one bottle of the fragrance every minute in its opening week, making it one of the store's best-selling celebrity products.
The exclusive launch of the 'Boyfriend' singer's scent also prompted a dramatic rise in online traffic and a 132% sales increase compared to the company's figures a year ago.
Michelle D'Vaz, National Advertising and PR Manager at The Perfume Shop, said: "With the remarkable success of JB's debut scent Someday, we are thrilled to say all records have been broken with the launch of Girlfriend.
"The online traffic has been remarkable and with one bottle being sold every minute it is safe to say Bieber fever is still a phenomenon!"
Girlfriend Justin Bieber is available in EDP Spray 30ml, 50ml and 100ml, priced at £23.50, £28.50 and £38.50 respectively via The Perfume Shop's website.
Bieber's first women's perfume Someday racked up over $3 million (£1.8 million) in sales after less than a month.
The 18-year-old previously revealed that he is "not interested in making a men's fragrance".
