Baby No. 3 is on the way!

Teen Mom 2 star Leah Calvert, 20, is expecting her first child with husband Jeremy Calvert, 23, this winter, the MTV star confirms exclusively to Us Weekly.

"Jeremy and I are excited to be adding a new addition to our family," Calvert (whose maiden name is Messer) tells Us. "Being a teen mom was difficult, but I'm older and in a different place now -- married to Jeremy and excited for our family to grow."

The reality starlet filed for divorce from her first husband, Corey Simms -- the father of her two-year-old twins Ali and Aleeah -- in April 2011. She tied the knot with Calvert one year later in Catlettsburg, Ky. in April.

"Ali and Aleeah can't wait to meet their new brother or sister," Calvert adds. "We feel incredibly blessed and look forward to this next chapter in our lives."

The third season of Teen Mom 2 is set to premiere Nov. 12 on MTV.
