Leah Messer took to Instagram on Sunday to wish dads a Happy Father's Day. However, she didn't mention either of her ex-husbands, Corey Simms or Jeremy Calvert.

As her twins, Ali and Aleeah, spent time with Simms, Messer posted a meme to dads all over the world.

"Happy Father's Day to all of the amazing DADS out there!!!" Messer wrote on Instagram in the caption of a meme, which read, "Any man can be a father but it takes someone special to be a dad."

Days prior, Messer revealed that she had taken a vacation and traveled to Massachusetts after a short trip to Nashville weeks ago for the CMT Music Awards.

"I've learned to always move forward in the direction that feels right and never look back! Follow the path of love, peace, and serenity!" Messer wrote in the caption of one of her vacation photos. "Be the best version of you! #liveyourstandard #livewellwithleah #peace #love #serenity #neverlookback #motivationalquotes."

Messer shares her seven-year-old twins, Ali and Aleeah, with her first husband, Simms, and four-year-old, Adalynn, with her second husband, Jeremy Calvert.

As fans may recall, Calvert announced his engagement to Brooke Wehr during the seventh season of Teen Mom 2 but earlier this year, the couple split after a messy cheating scandal that played out in front of fans on Instagram.

Now, months later, after facing tons of backlash from fans, Calvert has deleted his account entirely.

Throughout her time on Teen Mom 2, Messer's storyline has been plagued by different cheating scandals.

In 2011, she and Simms parted ways after she admitted to cheating on him just days before they wed. Two years later, they got engaged in an affair with one another while Simms was married to wife Miranda. Then, in 2014, Messer was accused of cheating by Calvert and months later, their divorce was finalized.
