According a report from Touch magazine, Jamie Lynn Spears' fiancé cheated on her during her pregnancy. The juicy piece of information was provided by the woman with whom Casey Aldridge cheated on his fiancée.

The 28-year-old woman named Kelly Dawson told the above-mentioned magazine that she was sleeping with Aldridge when Jamie Lynn Spears was six months pregnant. According to the woman’s account of events, Aldridge began pursuing her when he was already involved with Jamie Lynn.

“He totally instigated it and pursued me," Dawson told reporters. She added that Aldridge and Jamie Lynn weren’t exactly love birds from the beginning. During the first period of their relationship they were kissing randomly, but the two weren’t really into it until the spring of 2007.

Britney Spears’ first husband Jason Alexander told Touch magazine that Kelli and Casey had formed a very united couple for several years until Jamie Lynn came into the picture. The two stopped sleeping together before the last months of Jamie Lynn’s pregnancy period.

“It just didn’t feel right,” Dawson said.

“He had to deal with the baby coming, and it had to stop.”
