She spent a good portion of her life being known as Britney Spears' little sister, but now Jamie Lynn Spears is the one turning heads.

The 24-year-old attended the American Country Music Awards in Arlington, Texas last night and looked absolutely stunning in a form-fitting black lace gown. Her hair was elegantly pulled to the side in a ponytail and her makeup looked flawless. It's easy to forget about her superstar older sister when looking at these photos!

The former Nickelodeon star held onto her husband, 32-year-old Jamie Watson, tight as the couple happily posed on the red carpet last night.
