It's Really Over! Leah Messer Reportedly Served With Divorce Papers, Mistakes Process Server For Fan

Leah Messer and Jeremy Calvert's break up just became all too real.

The Teen Mom 2 star, 22, was reportedly served with divorce papers in a Smith's grocery store parking lot in Elkview, West Virginia, on April 14.

According to In Touch, Messer initially thought the process server was a fan looking for an autograph!

“At first, Leah was happy, excited even, but when she realized why she was being approached, her mood totally turned around,” an insider tells the magazine. “She was clearly pissed.”

Calvert, 26, who has been working as a pipeline engineer in Ohio in recent weeks, allegedly filed in Roane County, West Virginia, where the couple once lived with their 2-year-old daughter, Adalynn, and Messer's twin girls from her previous marriage, 5-year-old Ali and Aleeah.

As RadarOnline.com previously reported earlier this month, Messer and Calvert spent their third wedding anniversary apart, and both stopped following each other on Twitter.

But trouble loomed months before the rift. Calvert publicly accused his wife of cheating with an ex in October, and then in a bombshell report, RadarOnline.com revealed that the young father attempted to arrange a sexy sleepover with single mom Britany Musick.

Though she's so young, this is Messer's second divorce. She split from her twins' father Corey Simms after just five months of marriage in 2011.
