Leah Messer pregnant, engaged? 'Teen Mom 2' star is cryptic

A report is circulating that Leah Messer, one of the stars of MTV's "Teen Mom 2," is engaged to boyfriend of six months Jeremy Calvert and that they are expecting. Leah is already mom to twin two-year-olds Aliannah and Aleeah, by her now-ex-husband Corey Simms.

But is this report true? There is much speculation, based on one of Leah's tweets, that it is true, but that she is staying mum on the subject. Leah tweets:

"If I never trusted you before, what makes you all think I can trust you with this. #SadButTrue."

What do you think, "Teen Mom" fans? And also, do you think Leah's ready for yet another baby? Three before you are even 20 years old seems like a lot to us.
