Jamie Lynn Spears’ maybe baby daddy, Casey Aldridge, is being called a “serial cheater.” The eighteen year old construction worker has stepped out on Jamie Lynn with at least three other girls, and even impregnanted one of them. (Eighteen and already knocked up two chicks..Does someone need to sit this kid down and teach him how to use a condom?! Seriously.) This definitely sounds like one for Maury, they could take care of the paternity test and hook his butt up to a lie detector all in the same segment.

“I think Casey is a serial cheater who lied to Jamie Lynn and betrayed her time and time again,” an angry pal snitches to The National Enquirer.

“Even though in her heart she knows that Casey’s a lying, cheating dog, Jamie Lynn is head over heels in love with him. She continues to take him back regardless of how awful he treats her.”

“The past spring Casey was forced to tell Jamie Lynn that he’d cheated and gotten the girl pregnant….The girl miscarried several months later, but Jamie Lynn had already taken Casey back two weeks earlier.”

“In fact, only a few months before getting that girl pregnant, Casey had cheated on Jamie Lynn by dating another girl, Whitney Seals of Magnolia, Mississippi.”

The Enquirer claims “cheating” Casey was banging the bejesus out of eighteen year old Whitney, a college student, even after Jamie Lynn told him the news of her pregnancy.

Even Whitney’s brother, Kevin Seals, has stepped forward to drop a dime:

“Whitney and Casey have been dating for months,” Kevin tells the tab.

“Casey managed to keep his dates with Whitney quiet for about a month, but rumors started getting back to Jamie Lynn after he took Whitney to an LSU football game and they partied with some of his and Jamie Lynn’s best friends,” The Enquirer mole says.

“Jamie Lynn wants to believe that Casey is going to start acting responsibly, but judging by his history of cheating, that just isn’t going to happen.”
