It's Officially Over: 'Teen Mom 2' Stars Leah Messer & Jeremy Calvert Finalize Divorce In Court, MTV Crew Shows Up To Courthouse

Leah Messer is officially a single woman.

The Teen Mom 2 star's divorce from estranged husband Jeremy Calvert was finalized on Monday, insiders say— and RadarOnline.com has all the exclusive details.

"Jeremy attended the hearing, but Leah did not," a source tells RadarOnline.com of the troubled mother of three 23, who is currently undergoing treatment in a rehab center across the country.

And naturally, MTV was on hand to capture the West Virginia couple's latest drama.

"An MTV crew was stationed outside the courthouse," an insider reveals. "The judge was angry because he found it disruptive."

The divorce documents were sealed to prevent the public from learning the truth behind Messer and Calvert's nasty split.

But RadarOnline.com readers already know the couple's dirty little secrets. The father of Adalynn, 2, was caught sexting hot single mom Brittany Musick, and even hooked up with west coast tattoo model Melissa Marie.

He wasn't the only cheater: Messer's ex, Robbie Kidd, claimed he and the mother of three had sex last fall.

As RadarOnline.com exclusively reported, Calvert first filed for divorce on November 17, 2014.

He is now dating Ohio single mom Brooke Wehr, 24, RadarOnline.com recently revealed.

Meanwhile, Messer is finally getting help for what sources exclusively tell RadarOnline.com is a prescription painkiller habit.

She was previously married to Corey Simms, the father of her 5-year-old twins, Ali and Aleeah, for just five months before they split in April 2011.
