Taylor Swift is 21, y'all! Now, instead of frequenting coffee shops and Chuck E. Cheese for their dates, rumored boyfriend Jake Gyllenhaal can take her out for grown-up martinis at Hollywood dive bars. However, we're still not sure if her curfew's moved all the way to midnight yet. All jokes aside, we'd probably take a shot with her, too—in both the alcoholic and relationship sense. She's cute, family-oriented, and we wouldn't mind being immortalized in a song. Hell, we need to leave some legacy behind if our whole "career" thing falls through. But enough about our needs; today we celebrate Taylor. Without any further interruption, click through 21 of Taylor Swift's sexiest pictures—one for each of her sweet and innocent years (that'll soon be shattered by a night of heavy drinking).
