Leah Messer is moving on pretty quickly from her divorce to Corey Simms -- by reportedly getting engaged and pregnant with someone else!
The "Teen Mom 2" star, who already has 2-year-old twins Aleeah and Aliannah with Simms, is currently expecting baby #3 with brand new fiance Jeremy Calvert.
According to Us Weekly and Teen Mom blog TeenMomTalk.com, Jeremy popped the question over the holidays.
Messer has yet to confirm the news herself, but Jeremy reportedly told Reality Weekly "Yes, Leah is having my baby! I was at work when Leah called to tell me. She’d gotten blood work done and it came back positive. At first I was kind of surprised -- but I was happy.”
Jeremy also says he got her a 1.5 carat princess-cut diamond and presented it to Leah on Christmas Day.
