'Teen Mom 2' Star Leah Messer Suffers A Miscarriage

"Teen Mom 2" star Leah Messer and fiance Jeremy Calvert are going through a difficult time. Weeks after the couple confirmed they were expecting a baby, Calvert has revealed that Messer suffered a miscarriage.

"It's a devastating experience, but all I can do is support Leah and take things day by day," Calvert told OK! about the sad news. "It's hard, but we will get through it."

Messer, 19, stars on the popular MTV show chronicling the lives of young mothers and has two-year-old twin girls, Aliannah and Aleeah, with her ex-husband, Corey Simms. According to OK!, Messer had a difficult pregnancy the first time around, and was put on bed rest after going into early labor when she was six months pregnant.

Though she's going through a rough time, Messer recently tweeted about how proud she is of her daughters.

"I am such a proud mommy!" she wrote. "I literally have THE BEST two little girls in the whole world! God couldn't have gave me anymore of a blessing!!"
