RED-CARPET DEBUT

After quietly dating, Jamie Lynn and boyfriend Casey Aldridge made their red-carpet debut in June 2007 at the premiere of Nancy Drew. Aldridge, who is believed to be 18 or 19, grew up in Liberty, Miss., about 30 miles from the Spears family home in Kentwood, and played baseball and football in high school. He was often seen at the Southern California condo where Jamie Lynn stayed with her mother, Lynne, while filming Zoey 101, and would visit the actress on the set.
