A "Bachelor" baby is on the way.

Jason and Molly Malaney Mesnick are expecting their first child together, they told People on Thursday. The baby is due in March.

Mesnick, 36, also shared the baby news via Twitter:

Ty is Mesnick's son from a previous marriage.

Twenty-eight-year-old Molly Mesnick also took to Twitter, saying they were excited "about the pint size peanut on the way."

The couple met on the 13th season of "The Bachelor." Molly was actually the runner-up to the winner Melissa Rycroft. Mesnick proposed to Rycroft but ended up breaking up later, saying he still had feelings for Molly. The two married in February 2010.
