For years, fans have watched as Leah and Corey have tried to figure out what’s ailing their daughter Ali, who struggled with her motor skills. Although most doctors were only able to say what Ali wasn’t suffering from, we now know that Ali does have a diagnosis. She is also making leaps and bounds in her development!

It was shocking when Leah Messer and Corey Simms called it quits in April 2011, because they seemed to working out. Now Leah’s married to Jeremy Calvert, and has reportedly given birth to her third child. At the end of Teen Mom 2 Season 3, it’s become apparent that Leah still wasn’t over Corey, even when she moved on with Jeremy.

Last Season it looked like they split up after Corey found out that Leah cheated on him with her ex-boyfriend Robbie Kidd. Now it seems that that wasn’t the reason for the split.

Leah Messer and her ex-husband have a long history and two children together so when she moved on to Jeremy Calvert in August of 2011, she dealt with some mixed emotions. No one knew how long she had feelings for Corey, but as Teen Mom 2 progresses we’re starting to see that Leah was still in love with Corey even after she and Jeremy Calvert became engaged and pregnant.

It may be hard for viewers of Teen Mom 2 to believe as we follow Leah Messer and Corey Simms on their emotional roller coaster ride ending in divorce, but these current episodes were filmed more than a year ago and both Leah and Corey have moved on and are in stable new relationships. Leah is remarried to Jeremy Calvert and ***SPOILER ALERT*** expecting another child, and it appears that Corey is following close in her footsteps by proposing to his girlfriend of more than six months, Miranda Patterson!

Leah Messer-Calvert is currently married and expecting a child with Jeremy Cavert but on the upcoming season of Teen Mom 2 which was shot over a year ago, she’s just getting divorced and trying to move forward with life without the father of her children, Corey Simms. In a recent interview, Leah reveals what fans can expect from her in the upcoming third season and the other girls give us an update on their lives.

Leah Messer-Calvert is currently married and expecting a baby with her husband, Jeremy Calvert, but her road to happiness hasn’t been easy. Leah, who is just 20-years-old, is on her second marriage and has two children with ex-husband Corey Simms, who she cheated on just days before their wedding. Most of her story has been seen on episodes of 16 & Pregnant and Teen Mom 2, but in case you missed anything, we’ve got all of the details of her love life laid out in a timeline starting with the moment she met her first husband.

Anyone who has watched Teen Mom 2 knows Leah Calvert and Corey Simms’ daughter Aliannah has had to deal with all sorts of medical issues and tests — quite the load for a 2-year-old! (Not to mention her family!) Fortunately, after a couple of years of tender loving care, Ali has remained strong and is now doing better than ever. Just a couple of months after her twin sister Aleeah began walking, Ali is taking her first steps! Keep reading to watch the brief clip of Ali’s first steps and get the reaction from some of those closest to her!

Leah Messer got married to her man Jeremy Calvert in a secret ceremony in early April and now it appears her ex Corey Simms may have found true love in the arms of… a police officer?!? Keep reading to meet Miranda Patterson, a 21-year-old blonde beauty who just recently became the newest gun-toting employee of the Mason County Sheriff’s Department in Point Pleasant, West Virginia! Plus, read Corey and Miranda’s mushy tweets after what appears to be one of the best first dates in history!

Back in the day after Corey Simms split from Teen Mom Leah Messer, rumors leaked that he and 16 & Pregnant cast member Nikkole Paulun had a tryst. At the time it didn’t amount to much more than innuendo with Simms dismissing it by claiming that Paulun was harassing him. In the midst of all that Paulun caught some serious hate as many fans of the show labeled her a homewrecker among other things. Even though a lot of time has passed, this obviously still bothered Nikkole as she decided to post a couple of old Skype screen grabs over the weekend in which Corey directly propositioned her for sex. See the caps in question and read Nikkole’s explanation as to why she posted them after so much time had passed. Also read Corey’s response to the whole thing here.

Tonight is a special 90-minute episode of Teen Mom 2 in which Leah Messer files for divorce from husband Corey Simms – something fans knew was coming since last April when their filing was published in a local newspaper. Before we all have our hearts broken all over again watching this young couple shatter and split, I thought we might take a short trip down memory lane with some photos from their wonderfully West Virginia wedding ceremony.
