Leah Messer appeared to be ready to ditch her rumored boyfriend, T.R. Dues, for her ex-husband, Jeremy Calvert, during Monday's Teen Mom 2, but unfortunately, Calvert had no such plans.

Instead, Calvert has set his sights on his relationship with Brooke Wehr, which is currently going strong after a brief separation at the end of last year, and according to a new rport, the Teen Mom 2 star and mother of three may be feeling a bit jealous.

"Anyone who's closely observed Ms. Messer's behavior over the past seven seasons knows that saying she's the jealous type would be putting it very mildly," The Hollywood Gossip reported on Tuesday. And, "many fans on Twitter speculated that Leah was so flirty with Jeremy simply because she's jealous of his new relationship," the outlet added.

Messer and Calvert parted ways at the end of 2014 after Calvert accused Messer of cheating and months later, he began dating Wehr. And while the couple did spend time apart at the end of last year, they were back on by January -- just in time to shut down rumors of a possible Messer-Calvert reunion.

“There’s no way in hell Jeremy wants to be back with Leah,” a source told The Ashley's Reality Roundup in January. “They rarely text, and when they do it’s only about Addie. As far as them calling each other ‘baby’ and all that, it’s completely untrue.”

As for Calvert and Wehr, the source explained, “They split for a little while but are back together right now and going strong. Brooke is really different from Leah and Jeremy is really happy with her. They have a lot of fun together.”

The outlet went on to reveal that while Calvert's job used to keep him out of town for weeks at a time, he has since taken on a new position which doesn't require as much traveling.

“He’s still working in the pipe lining business, but this position means less traveling for Jeremy, which is good for his relationship with Brooke,” the source said. “It will also give Jeremy a lot more time with his daughter.”
