'Teen Mom 2' star Leah Messer gives birth to Super Bowl baby

During last night's Super Bowl, while many were tweeting about Beyonce's halftime show, 20-year-old Leah Messer-Calvert was announcing the beginning of labor with her third child. "Yes, the time is near ... Can't wait to meet you little Miss Calvert," the "Teen Mom 2" star tweeted.

Leah gave birth to a baby girl in the early hours of Jan. 4, In Touch reports. A family friend tells the mag, "Mother and baby are happy and healthy. Leah went into labor late last night."

This is Leah's first child with husband Jeremy Calvert, though the pair has conceived in the past. The couple was expecting twins when Leah miscarried in 2012. They married five months later. A few months after the wedding, Leah announced she was pregnant again.

The new baby joins Leah's twin's from a previous marriage, Aliannah Hope and Aleeah Grace Simms. Congrats to the happy couple.
