Teen Mom Leah Messer has been pregnant three times — once back in 2009, a pregnancy that ended with the birth of her precious twin girls, Aliannah and Aleeah, on December 16, 2009. She was pregnant again in late 2011, but, sadly, miscarried in early 2012. She has never released details of that pregnancy. And now, as we head into 2013, Leah, one of the stars of Teen Mom 2, is pregnant again! She is due early next year. Leah was married briefly to the twins' baby daddy, Corey Simms, but that union did not work out. The father of the child Leah is carrying now is her second husband, Jeremy Calvert. He was also the father of the child she miscarried in early 2012, though they were not married at the time. But they are together now, and are awaiting the arrival of the new baby with joy and excited anticipation! Rumors are swirling that the pregnancy might end with another set of twins! We can't wait to find out!
