Did Jamie Lynn's BF Cheat on Her While She Was Pregnant

Where there's smoke, there's fire…

Rumorhas it that Britney's little sis Jamie Lynn was cheated on by her boyfriend - while she was pregnant!

Casey Aldridge claims that he never did the horizontal mambo with 28-year old Kelly Dawson while Jamie Lynn was preggers with Maddie Briann. Kelly claims that she and Casey were still hooking up until March of 2008. (FYI: Jamie Lynn gave birth June 19).

According to reports from InTouch:

Kelli says she and Casey stopped sleeping together a few months before Jamie Lynn gave birth to their daughter, Maddie. “It just didn’t feel right,” she explains. “He had to deal with the baby coming, and it had to stop.” She says the last time the couple had sex together was in March but “even after we stopped having sex, we would still kiss occasionally.

OMG! If this were true, what the hell is it about men being "vulnerable" while their girlfriend or wife is on the most vulnerable stage of her life - which is pregnancy? Aside from having to deal with morning sickness, hormones, mood swings, bloating and feeling like you're the size of an elephant - you have to deal with a cheating partner, too? Gimme a break!
