Jamie Lynn Spears
Unlike many star siblings, teen actress-singer Jamie Lynn Spears managed to step out of the long shadow cast by her older sister, pop phenomenon Britney Spears, and enjoy her own career success as a hugely popular teen idol. Jamie Lynn made early appearances in such projects as Britney's film debut "Crossroads" (2002), prior to joining the kids' sketch-comedy show "All That" (Nickelodeon, 1994-2005). Positive fan reaction led to her taking on the starring role on the popular tween TV show, "Zoey 101" (Nickelodeon, 2005-08), one of the network's best performing series in years. The success of the show quickly begat made-for-TV movie spin-offs like "Zoey 101: Spring Break-Up" (Nickelodeon, 2006). Then in 2007, Spears' unexpected pregnancy brought about the early demise of "Zoey 101" and prompted the 16-year-old starlet to return home to Mississippi with the father, Casey Aldridge, where she planned on marrying and raising their child. Neither the relationship nor the retirement were to last, however, as her planned marriage to Aldridge never materialized and rumors of Spears launching a career in country music began to swirl after her relocation to Nashville in 2010. Whether Spears' career would become a footnote to that of her sister's or would evolve via a rare second act remained to be seen.
