Leah Messer is back on Twitter.

'Teen Mom 2' Star Jeremy Calvert Shares 'Late Night' Work Photo

After a brief hiatus, the Teen Mom 2 star returned to social media last week, and this week, she posted an odd message to her fans.

"God knows!" Messer tweeted on Sunday night, along with a set of praying hands.

Did Corey Simms' Wife Just Diss Leah Messer On Twitter?

Since February, both Messer and her husband, Jeremy Calvert, were taking what appeared to be a much-needed break from social media. Last year, Messer came under fire after Calvert told Twitter fans she cheated on him with her ex-boyfriend, Robbie Kidd. Although Calvert eventually deleted the tweets, and Messer denied the affair, the couple's silence led many fans to believe they would soon divorce.

Then, months later, Messer and Calvert reunited to celebrate New Year's Eve together. Following the celebration, Messer surfaced on social media, where she shared several photos from their evening. Since then, Messer and Calvert appear to be back together and working on their marriage.

For the last several weeks, Messer and Calvert have been filming season six of Teen Mom 2, which is sure to fill fans in on what's really going on between them, as well as what's happening between Messer and her ex-husband Corey Simms.

At the end of last year, as Messer battled divorce rumors, she and Simms were in court fighting for custody of their twin girls, Ali and Aleeah.

Teen Mom 2 season six is expected to air later this year on MTV.
