Jamie Lynn Spears has reportedly been dumped by boyfriend Casey Aldridge over his fears that he may not be the father of her unborn child.

Jamie Lynn has never confirmed her sperminator's identity, and now Aldridge is demanding proof that he is the father, according to U.S reports.

Aldridge’s doubts were allegedly revealed by a pal of Jamie Lynn's troubled sister Britney Spears.

"He wants a paternity test," Britney told the Spears family friend, according to In Touch Weekly.

There has been speculation that Jamie Lynn is pregnant by an older TV producer.
