Warring ex-couple Leah Messer and Corey Simms of "Teen Mom 2" are on the news again after reports of their alleged "sexcapade" on the back of the latter's truck surfaced.

According to In Touch Weekly, the two were caught hooking up in their hometown instead of discussing the status of their twin daughters, Ali and Aleeah. An insider for the website revealed that the MTV's documentary series star had sex with her first ex-husband in the back of his truck when she was supposed to meet him to talk about their children.

Messler and Simms divorced after the former cheated on him with now ex-boyfriend Robbie Kidd. The media has followed their bitter feud for the custody of their twins. Simms has been very vocal about his distrust in his ex-wife, claiming that she was abusing prescription pain pills for her stress and anxiety therapy.

While Messler is currently a free agent after her recent divorce with husband number two Jeremy Calvert, Simms is still married to Miranda. Radar Online reports that the scandal has spread in West Virginia, forcing Simms to admit the affair to his wife of two years. As Miranda is reportedly pregnant, the whole situation has become "a huge mess" and even all their friends know about it.

Meanwhile, Dispatch Times reports that Messler is currently in trouble with the police following a tip from her kid's teacher. The "Teen Mom 2" star is said to be under investigation after consistently failing to bring Ali's wheelchair to school. It purportedly got to the point that her disabled daughter was not able to exit the classroom during a fire drill.

Ali suffers from an uncommon type of muscular dystrophy, making it impossible for her to get around on her own. Others complain that her mother has not been providing for her special needs, just like bringing a wheelchair to school. Also, Messler is reportedly always late in picking up the girls.

"Teen Mom 2" airs on Thursdays at 10 p.m. EST on MTV.
