Well, it appears she's back on the scene, and this time cultivating a singing career. Instead of delving into pop like her big sister, however, Jamie Lynn's picked country as her musical poison.

In Nashville, Tenn. last night she debuted I Look Up To You, a ballad she told the audience was inspired by her sister, Britney.

The lyrics speak to that time when Britney was shaving her head and attacking cars with umbrellas (Watch the video HERE)

"Scared little girl/ living in a big old world/ You've outgrown your room/ it all happened way too soon/ They took away your innocence/ We forgot our strong defense."

Wonder what her big sister thought of the performance?

Seeing as Brit Brit is rumored to be a pretty terrific judge on The X Factor, maybe she could give Jamie Lynn a few pointers.
