In the midst of her televised custody battle over her twin daughters on MTV’s “Teen Mom 2,” star Leah Calvert (formerly Messer) is also being faced with a barrage of hateful comments about her children and her mothering skills on social media. The 22-year-old reality-TV star and mom of three addressed some of the obscene comments on her Twitter account Monday night by screen-capturing the hateful tweets.

“This is always a great to read when you get on Twitter after not being on it a couple days. Bless their hearts,” said Calvert, alongside an image of some of the derogatory messages. The tweets, reportedly posted by user @faroutcry13, call Calvert a “poor excuse for a human being,” among other insults, some of which were directed toward her 4-year-old handicapped daughter, Ali Simms.

“I see your stupid worthless handicapped kid has her wheelchair bc she cant do s--t else thanks to you,” said the viewer. “You are a poor excuse for a human being. Abort your next kid you w---e. Worthless piece of s--t.” The Twitter user went on to call Calvert “scum” and expressed their hope for her to “roll over” and “die.” As of Tuesday, the user's account was suspended from Twitter.

The comments come on the heels of Calvert’s dramatic custody battle over her twin daughters with her former husband Corey Simms on Season 5 of "Teen Mom 2." On the series, Simms, 25, accused Calvert of not properly taking care of their special needs daughter, Ali, who suffers from a rare, incurable form of muscular dystrophy. Following Simms accusations that Calvert, who is also mom to daughter Adalynn, 1, with her husband Jeremy Calvert, had not been taking their daughter to therapy and school, he filed a petition against Calvert seeking full custody of Ali and her sister Aleeah.

“They have nothing against me that says that I’m a bad mother. They were confident that they were going to take my kids,” Calvert said of Simms following their courtroom battle on last Tuesday’s installment of “Teen Mom 2.” “He knows that I’m a damn good mom and I take them when they’re supposed to go.… He was like, 'It sounds to me like she’s an incompetent mom.’”

While the current custody arrangement between the pair is unknown, Calvert did hint that the case leaned in her favor on Twitter last month following reports that Simms had attempted to use her prescription drug use against her in court. “The BEST divorce and custody lawyer! @DivorceLawyerWV,” Messer-Calvert said Aug. 7. “It shouldn't take being legally appointed to benefit your children's needs. All I can say is I would be ashamed as a parent/grandparent,” she posted on Facebook Aug. 11.

The hearing is set to unfold further on the Season 5 finale of "Teen Mom 2." The episode airs Wednesday at 10 p.m. EDT on MTV.
