Give the girl her whiskey and denim! In the new Us Weekly Style issue, country superstar Jana Kramer spills on her denim obsession and the secret to dressing up her jeans.

"I probably have 80 pairs," Kramer, 30, tells Us of her massive jean collection. "I have a denim junk drawer!"

The Nashville-based star doesn't only reserve them for casual weekend style; the "Love" singer dresses them up and down. "I never wear a dress going out," Kramer tells Us.

Instead, date nights with her NFL player boyfriend Michael Caussin and girls' nights will consist of the country crooner in a black blazer, heels, and her favorite J Brand or Rag & Bone skinny jeans. "It's my favorite look," says Kramer, whose new album is due later this year.
