Leah Messer is a third-time mom! The Teen Mom 2 star welcomed her first child, a baby girl, with new husband Jeremy Calvert on Monday, Feb. 4, a source confirms to Us Weekly.
"Yes, the time is near," the MTV star tweeted Sunday of her daughter's impending arrival. "Can't wait to meet you little Miss Calvert!"
Stay-at-home mom Messer shares twin daughters Aleeah and Ali, 3, with ex-husband Corey Simms, whom she divorced in April 2011. She married pipeline engineer Calvert a year later in June 2012.
"There is a reason God gave the baby to us now," Messer told Us Weekly exclusively in November 2012 of her third pregnancy. "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. It'll be Jeremy's parents' first grandchild, so they're really excited."
The Elkview, W. Va. native, who first appeared on season two of 16 and Pregnant in 2010, told Us that she felt ready to have another child despite her young age.
"The path I chose isn't right for everyone, but it's right for me," she explained. "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."
