Britney Spears wasn't lying when she teased that her December 3 album release, [article id="1715594"]Britney Jean[/article], will be her [article id="1716237"]most personal release to date[/article].

The Spears sisters will join forces on [article id="1717333"]"Chillin' With You."[/article] It also marks Jamie Lynn's first big return to the spotlight since [article id="1578981"]ending her hit Nickelodeon show, "Zoey 101,"[/article] in 2008 to [article id="1576746"]raise her daughter, Maddie[/article], who turned 5 years old this summer. In the years since, Jamie Lynn has been trying to work on her country music career, even living part time in Nashville and playing small shows.

In November 2011, she took the stage for the first time in Nashville, and in June 2012 she performed at a showcase at the Music City's 3rd & Lindsley Bar & Grill. It was there that she debuted the track, "I Look Up to You," which was inspired by her older sister.

That same year, she dished to Glamour about her country music debut, which had been originally slated to drop in 2012.

"I'm more honest in my lyrics than I am in anything else," she said. "It's where I feel the most safe to express myself. I write about growing up, my family, Maddie and getting pregnant. If I've lived it, why wouldn't I talk about it? I guess that's been the coolest thing, realizing that it's OK to just be myself and really tell my story."

While the album has yet to get a release date, Jamie Lynn seems excited for this next chapter of her career. Shortly after Britney tweeted out her track list on Tuesday, Jamie Lynn added, "I'm excited to work with my sis, but even moreee excited for y'all to hear what I've been working sooo hard on the past 5 years! #staytuned."
