She may be country's queen, but she's no country bumpkin -- singer Taylor Swift soars in sexy styles for the November issue of Glamour.

The blonde-haired beauty wears a black lace Tadashi Shoji dress with a Jennifer Fisher Jewelry telephone-cord bracelet on the magazine's cover, while inside the pages, the 20-year-old dons a variety of chic adult looks.

Among them: a flirty blue Dior frock with a sequined bodice; a shiny black Jason Wu shirt with sleek L'Agence leggings and Christian Louboutin heels; and a '60s-inspired black Valentino cocktail dress with dotted netting accessorized by a beehive hairdo and Jimmy Choo kitten heels.

During her Nashville photo shoot, Swift, who was snapped by Matthias Vriens-McGrath, turned playful, skipping, hopping, dancing, and singing along to songs including Phoenix's "1901." And in a behind-the-scenes video from the shoot, the singer spills her style secrets.

"One of the things that makes me feel glamorous is a dark lip, like red lips... There's something that that adds," says Swift, before holding up a black, beaded heel. "And also these shoes. They're not mine. They're Dolce & Gabbana. They put these out as options for me to wear today. And I was like, 'Those, please!'"

The CoverGirl spokesmodel, whose new album "Speak Now" arrives in stores Oct. 25, also reveals how she maintains her marvelous mane.

"I don't really do much to it because my hair is naturally curly," she says. "So unless I'm straightening it -- and that's only in the wintertime -- I just kind of leave it the way it goes naturally. But I'll correct a few of the curls that are going the wrong way with a curling iron."

If only her relationships were so low maintenance!

The Grammy winner, who has had high-profile romances with stars including Joe Jonas and Taylor Lautner and has been known to write a song or two about her exes, admits that she's been hurt in the past but doesn't dwell on heartache.

"I've been careful in love. I've been careless in love. And I've had adventures I wouldn't trade for anything," Swift tells Glamour. "I've learned that you can't predict [love] or plan for it. For someone like me who is obsessed with organization and planning, I love the idea that love is the one exception to that. Love is the one wild card."
