Wow, that Lynne Spears sure was smart to go running to OK! Magazine when she learned her 16-year-old daughter was pregnant. Since then, Jamie Lynn has been able to nab two more covers of the celeb-friendly magazine: the first one to premiere her baby with fiance Casey Aldridge, Maddie, and the latest to combat all the stories about Casey’s serial cheating. Jamie Lynne and Casey are on next week’s cover, looking like the perfect, airbrushed couple, to “set the record straight” about Casey’s alleged extracurricular activities.

In a rare, exclusive interview, new parents Jamie Lynn Spears and Casey Aldridge have reached out to OK! to defend themselves and their relationship against the tidal wave of rumor that has nagged them since the June 19 birth of their adorable baby daughter, Maddie Briann.

A recent series of scurrilous tabloid stories have alleged that not only has 19-year-old Casey been unfaithful to Jamie Lynn, but that he’s also gotten another woman pregnant. The stories insist that the couple’s relationship is a sham and that he is still seeing other girls!

On the topic of former friend Kelli Dawson, who claims to have been romantically involved with Casey, even after Maddie’s birth, he tells OK! these allegations of infidelity are “not the least bit” true.

“In a small town, everybody knows everybody,” he explains. “But when money’s involved, you find out who your friends are.”

As for reports he impregnated Kelli, a stunned Casey told OK!, “That’s news to me.”

“That is just completely fabricated,” adds Jamie Lynn. “He never had an intimate relationship with her, so how would that be possible? Around here, that particular girl is known to make up stories.”

And then there’s Whitney Seals, who supposedly romanced Casey. Says Jamie Lynn, “What happened was that one of those girls did it, and in this small town when one of them does it, they’re all like, ‘Good idea.’ They all jumped on the bandwagon.”

The tall tales have taken their toll on the young parents. “It hurt me to hear those things,” reveals Jamie Lynn to OK!. “Because my family has to read it. It’s not fair to them.”

Another factor making things worse is that the Aldridge family has been thrust unwillingly into the spotlight. “Casey’s family is not used to this,” the former Zoey 101 star explains. “They might assume it’s true. My family knows it’s not. It was definitely harder for Casey’s family to deal with it, but you just explain that it is part of this business.”

The new mom says that her family has stood beside her through the entire ordeal. “They know if I were in a relationship like that, I wouldn’t put up with it,” she tells OK!. “My family supports me, and they support Casey also. They read those stories and take them with a grain of salt.”

Notice how Jamie Lynn does most of the talking here – which is odd, considering the rumors are all about Casey. And rather than presenting some concrete proof, the couple just categorically denies everything and calls these other women liars. “That’s news to me,” isn’t exactly an iron-clad alibi – especially when the girl, Kelli Dawson, supplied intimate photos of herself with Casey and could name specific days and locations where she and Casey would meet up. To me, this whole interview rings false- if there’s nothing there but complete fabrication, then Jamie Lynn and Casey should have easily been able to prove it. Perhaps they would have done themselves a greater service to stay silent.
