Here’s another one. Just weeks after being accused of a tawdry sexual affair with a woman a decade his senior (Kelli Dawson), Jamie Lynn Spears’ 19-year-old fiance is on the hot seat again as a 20-year-old blonde beauty queen accuses Casey Aldridge of having sex with her in his pickup truck seven days after Jamie Lynn delivered the couple’s daughter, Maddie.

“Casey is a womanizer and a player who can’t kepp it in his pants,” Andrea revealed to the National Enquirer.

Andrea attended the same Liberty, Mississippi high school that Casey did, she insists she and the new dad have had a “purely sexual” relationship for the past four years, unbeknownst to Jamie Lynn.

“Casey hit on me every time he saw me…He threw himself on me and foolishly we ended up making love almost every time. During our romance, Casey was sleeping with as many as four other girls besides Jamie Lynn. All Casey can think about is the next person he’s going to have sex with.”

When baby Maddie Briann was one week old, Casey allegedly “lured” Andrea to a friend’s house under the gist of needing her help with something-the two ended up butt naked in the bed of his pickup.

“First, he persuaded me to stick around and hang out with him and his friend. The he lured me out to his car and asked me if I wanted to go for a drive. Once we were in the truck, Casey was unrelenting. It was stupid, but we ended up having sex.”

Andrea says Casey openly admits that the Spears’ money bags are the only thing keeping him with the 17-year-old Jamie Lynn.

“During the holidays and birthdays, Casey always made sure he was with Jamie Lynn so he would get big expensive gifts from her and the Spears family.”
