Even while Jamie Lynn Spears was pregnant, Casey Aldridge cheated on her with older woman Kelli Dawson who openly talked about it with “In Touch” magazine.Wow! That’s just thick! I can totally relate because when I was pregnant I felt like a cow and I bet I looked like a cow too but that’s just not right!Sure Kelli Dawson is quite hot but that’s just no excuse. Casey Aldridge is a pig and Jamie Lynn should just dump him.Kelli and Casey deserve each other from all the “sexual attraction” they keep talking about, apparently that must be the only thing Casey wanted from Jamie Lynn as well. Only problem was the younger Spears was stupid enough to get pregnant while the hot older woman can just keep on doing what she does best.Somebody there sure wants some publicity to come out at this time when all seems well.
