Sad news for "Teen Mom 2" star Leah Messer: She just suffered a miscarriage.
Messer's fiance, Jamie Calvert, confirmed the news to OK! Magazine -- telling them ""It's a devastating experience, but all I can do is support Leah and take things day by day."
He adds, "It's hard, but we will get through it."
The 19-year-old reality star, who has two twin girls with ex-husband Corey Simms, hasn't spoken out about the news yet -- but tweeted lyrics to a Reba McEntire song last night, writing "I'm a survivor!"
Earlier in the week, Messer also tweeted about daughters Ali and Aleeah, writing "I am such a proud mommy! I literally have THE BEST two little girls in the whole world! God couldn't have gave me anymore of a blessing!!"
