Britney Spears poses seductively in an ad for her brand new perfume, HIDDEN fantasy


The scent - described in a press release as being "all about expressing the many, mysterious sides of a woman" - will hit stores January 2009. In the television ad, Spears, 26, will appear through trees in a forest and ask, "What do you have to hide?"

Spears already has six perfumes: Curious, Fantasy, In Control, Midnight Fantasy, Believe and Curious Heart. Her original, Curious, earned $100 million in sales in the five weeks after its 2004 release.

The singer has been hard at work on her next album, Circus, which will drop Dec. 2 (her 27th birthday). The first single, Womanizer, premiered on NYC's Z100 radio station Sept. 26.
