'Pretty Little Liars' Lucy Hale covers 'Teen Vogue,' feels 16 going on 35

Just in time for the return of "Pretty Little Liars," 21-year-old star Calvin Klein-clad Lucy Hale graces the February cover of Teen Vogue (on newsstands Jan. 4).

And inside the issue, the actress teases at rumors of a possible music career. "All I can say is that if I ventured out into that world, it'd be a dream come true," she says. "When I'm ready for it, I'm going to dive into it 100 percent."

So what musicians do it for her? Taylor Swift, for one. "She's amazing -- listening to her songs is like reading a girl's diary. We've gone through a lot of the same relationship things."

But that doesn't mean that Hale would ever sing cutesy tunes about young love. She tells "Teen Vogue" that she has a mature sensibility, something that actually drove her to play her "PLL" character, Aria.
