'Teen Mom 2' star Leah Messer gives birth to a baby girl

It's another girl for Teen Mom 2 star Leah Messer. Messer gave birth on Monday, February 4, with new husband, and the baby's father, Jeremy Calvert, at her side.

The Teen Mom star has twin girls, Aliannah and Aleeah, 3, with ex-husband Corey Simms. According to E! Online, the pair married after the birth of their twins, but divorced only six months later.

Messer previously shared details on the pregnancy with Us Weekly saying, “There is a reason God gave the baby to us now. I'm not going to say it wasn't planned, because we intended to try -- eventually. It just happened a little sooner than we expected. Our parents are thrilled.”

While fans and critics alike may think that Messer, 20, is too young to have three children the mom shares, “The path I chose isn't right for everyone, but it's right for me. I am financially stable -- we just bought our first home -- and I'm emotionally fit to have another child. I'm 100 percent prepared -- way more than I was at 16."

Messer and Calvert married in June 2012. This is the couple's first child together.
