As we mentioned earlier today, rumors were circulating that Jamie Lynn is knocked up again! Sources close to Spears insist she's not sperminated, but the editor-in-chief of the National Enquirer loudly proclaims to us that their pregnancy story is true. Jamie Lynn is all over the news these days! The teen mom is also on the cover of the new issue of OK! magazine, and now we have more details from her on-the-record interview with them. Spears and babydaddy Casey Aldridge are speaking out about the cheating rumors that have plagued their relationship. The two claim that Aldridge is not a cheater and that Jamie is not pregnant again. The 19 year-old Aldridge claims that he did not have sex with "former friend" Kelli Dawson, even though she spoke on the record, confirming the two hooked up even after little Maddie was born. Aldridge says that's just not true, adding, "In a small town, everybody knows everybody. But when money's involved, you find out who your friends are." We think famewhore Kelli Dawson should take a lie detector test and prove Aldridge is lying, if he is. We'd even pay for the test! And as for the reports that he got Dawson preggers, Jamie says, "That is just completely fabricated. 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." Ouch. Called a liar nationally by teen mom Jamie? We think Kelli should definitely take a lie detector test now! As for rumors that Casey's been with other girls, Jamie denies that as well and adds, "It hurt me to hear those things. Because my family has to read it. It's not fair to them. They know if I were in a relationship like that, I wouldn't put up with it. My family supports me, and they support Casey also. They read those stories and take them with a grain of salt." And there you have it - until next week! [Image via Pacific Coast News Online.]
