We've long known that Britney Spears loves to play dress-up, whether donning an elaborate costume for a concert or sporting a series of retro outfits for a Pepsi commercial. And this week, the 30-year-old "Gimme More" singer gave us a double dose of glam getups, when she posted images from an Elizabeth Arden Fantasy Twist fragrance shoot on her Facebook page. The first photo saw the pop songstress unleashing her "inner Cleopatra." Britney later added a follow-up shot, in which she channels Old Hollywood in a spangly sequined dress and matching gold headpiece. "Jason says I look like Jean Harlow!" she commented. Last month, Spears shared a skin-baring bikini shot to show just how toned she's been looking lately.
