One of the stars of the popular MTV show Teen Mom 2 is pregnant again but this is even bigger news than if it had been any of her castmates…since she started off with TWO to begin with! 20-year-old Leah Messer has twins Ali and Aleeah with ex-husband Corey Simms, who she divorced in April of last year. She then remarried Jeremy Calvert this April. Married, divorced, re-married with twins and another on the way all by the age of 20! Imagine? SMH! “THANKS SOOO MUCH EVERYONE! #PositiveTweets makes this momma soooo happy!!! @Calvert505 are in such a good place! Love all of you!” she tweeted after sharing the news. As long as she’s happy, that’s all that matters! The new season of Teen Mom 2 kicks off November 12th.
