Jamie Lynn’s baby-daddy a ‘lying, cheating dog’

As if teenage pregnancy and train-wreck big sis Britney weren’t troubles enough, Jamie Lynn Spears can now add a cheating baby-daddy to her list of woes. According to National Enquirer sources, Casey Aldridge strayed from his young love a number of times, even dating another woman days before the 16-year-old “Zoey 101” star told the world she’s expecting.

“I think Casey is a serial cheater who has lied to Jamie Lynn and betrayed her time and time again,” a close friend confessed. “Even though I’m sure she knows in her heart 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.”

Just how awful is that? “This past spring Casey was forced to tell Jamie Lynn that he’d cheated on her and gotten that girl pregnant,” the same pal told the Enquirer. “Jamie Lynn was devastated. She swore Casey out of her life forever.”

Two weeks before the unnamed other woman miscarried, Jamie Lynn was said to be back in Casey’s arms with a promise that it would never happen again.

“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, Miss.,” a source revealed. That’s the same woman Casey’s been seen “sneaking around” with lately.

“Whitney and Casey have been dating for months,” Whitney’s brother Kevin Seals confirmed. “I know Jamie Lynn was really upset and jealous when she found out about it.”
