Britney's little sis, Jamie Lynn Spears, has reportedly split from boyfriend and baby daddy Casey Aldridge, according to US Magazine.

The cause of the breakup was not initially reported. However, a source for Star is now claiming that the former 'Zoey 101' star has dumped Aldridge for 28-year-old Louisiana business man James Watson, who lives relatively close to the Spears family estate in Kentwood.

"They started dating last December," the source said.
