Lady GaGa treated her French fans to a picnic in Paris on Sunday (23Sep12) to celebrate the success of her new perfume.

The Poker Face hitmaker's first scent, Fame, launched earlier this month (Sep12) and has sold more than six million bottles since it hit shelves.

Gaga staged a special event at a Sephora store in France's capital to toast her success on Sunday, and a group of specially-selected fans were allowed to join her.

They were treated to food and drink at the bash and the singer admits she is stunned by the reaction to her debut perfume.

In a series of posts on her Twitter.com page, she writes, "The reaction to Fame has been overwhelming. 6 million bottles in 1 week makes it the 2nd fastest selling fragrance after Coco Chanel.

"May we celebrate Coco, beauty & fashion on Les Champs Elysees w (with) picnic!"
