We can't believe it has been a decade since we first spritzed on Britney Spears' Fantasy fragrance, and to commemorate her 10th year in the fragrance business, the singer is releasing a special-edition anniversary bottle ($48; -- and you can win one signed by Britney herself! Only 100 bottles of the iconic jasmine, kiwi, and lychee blend were autographed by the singer, and here's how one lucky reader can score a piece of pop culture history: First, follow @InStyle on Twitter. At 3 PM today, tweet us using the hashtag #InStyleBritney and tell us which of Britney's songs contains the following (and oh-so-relateable) line: "It's been hours, seems like days, since you went away/And all I do is check the screen to see if you're okay." Be the first to tweet the answer to us at 3 PM EST today, and the autographed bottle could be yours! Read the official rules and details below. Good luck!
