On The Rebound! 'Teen Mom 2' Star Leah Messer's Estranged Husband Jeremy Calvert Dating Ohio Single Mom Brooke Wehr

That was fast!

Leah Messer and Jeremy Calvert split for the last time in March, and just over two months later, the Teen Mom 2 dad is settling down with a new girl.

RadarOnline.com can exclusively reveal that Calvert, 27, is dating Ohio single mom Brooke Wehr, 24.

The traveling pipeline engineer met the stunning Ohio University Eastern student while working near her hometown of St. Clairsville, sources tells RadarOnline.com.

And unlike Calvert's flings with West Virginia beauty Brittany Musick and tattoo model Melissa Marie, this new romance is quickly becoming serious.

“Both Brittany's and Jeremy's families know about the relationship,” the source reveals, adding that Calvert recently hung out with Wehr's family at Oasis Bar and Grill in Belle Valley, Ohio. “Her family approves of him.”

Like Calvert, Wehr is a parent. The brunette beauty has a 4-year-old daughter with her former fiance.

The father of Adalynn, 2, has been working and hanging out over the past several weeks with his new girl in eastern Ohio, about three hours away from his home base in West Virginia.

With his 23-year-old ex currently in rehab, RadarOnline.com recently reported that little Adalynn has been spotted with Messer's younger sister Victoria Jones, 20.

Calvert and Messer's nasty divorce will play out on the upcoming season of Teen Mom 2, premiering in July.
