Jeremy Calvert is back on Twitter -- and he's not looking forward to the latest milestone in his daughter's life.

'Teen Mom 2' Leah Messer Has Won Back Custody Of Her Twins

Ahead of Adalynn Faith Calvert's third birthday, the Teen Mom 2 star, who previously hinted he was quitting Twitter, took to social media, where he expressed his disbelief in the upcoming event.

'Teen Mom 2' Star Jeremy Calvert Confirms Relationship With Brooke Wehr With New Photo

Calvert and his ex-wife, Leah Messer, welcomed their first child together in February 2013, less than one year after they wed, and sadly, in 2014, the couple called it quits amid allegations of cheating (it was later revealed that Messer and her ex-husband, Corey Simms, engaged in an affair in 2013).

Following the end of his marriage, Calvert began dating Brooke Wehr, and after a brief split at the end of last year, the couple is back on.

“They split for a little while but are back together right now and going strong,” a source told The Ashley's Reality Roundup last month. “Brooke is really different from Leah and Jeremy is really happy with her. They have a lot of fun together.”

“They’re in no rush to live together or anything like that,” the source continued. “They both have daughters, so they want to make sure that they are going to last before they move in together and get the kids involved.”

Jeremy Calvert returns to MTV later this year in Teen Mom 2 season seven.
