Casey Aldridge Cheated on Jamie Lynn Spears with Kelli Dawson Interview

In an explosive new interview, Kelli Dawson says Casey Aldridge has been having sex with her throughout Jamie Lynn's pregnancy and for the past two years.

In an exclusive interview with In Touch, 28-year-old Kelli Dawson reveals that she and Casey, 19, were romantically involved — and were still sleeping together when Jamie Lynn, now 17, was six months pregnant with his child.

The pair first met in November 2006. At the time, Casey was already dating Jamie Lynn, but the sexual chemistry between Casey and Kelli was instant. “We were both really attracted to each other,” Kelli reveals.

“He totally instigated it and pursued me. His friends would tell me that he liked me, that he thought I was pretty.” It wasn’t really “hot and heavy,” Kelli admits, until the spring of 2007.

The pair didn’t bother to hide their relationship. “Kelli and Casey have been a couple on and off for a few years,” confirms Jason Alexander, Britney Spears’ first husband.“They were a really tight couple, but I think it was hard for Kelli, having Jamie Lynn in the picture.”

Well, Jamie hasn't gotten married yet. She still has time to run. That's how these country folk do it. When these sluts aren't giving oral to their cousin or stepbrother, they're sleeping with a friend whose girlfriend is knocked up. Kelli's a 28-year-old, then 26, banging a 17-year-old?! Redneck, trailer trash, skank!
