Meghan King Edmonds is going to be a mom!

The 31-year-old Real Housewives of Orange County star announced she's expecting her first child with her husband, former pro baseball player Jim Edmonds, on Monday, with a sweet Instagram post. The couple is expecting a baby girl.

"IVF has been a journey. We are so grateful and happy to share our news," Meghan tells ET exclusively.

"We're expecting a perfect little bundle of sugar and spice and everything nice!" Meghan captioned a picture of the couple staring lovingly at her growing baby bump. "Jimmy and I are over the moon! We are thrilled to bring our daughter into our perfectly imperfect blended family in time for the holidays!"

Meghan has been open about going through IVF in order to make her dream of becoming a mother a reality. ET caught up with her last Thursday in Los Angeles, when she talked about her personal struggles.

"You know, IVF is really, really difficult emotionally, physically, and I like to think of IVF as not having an end, but really just having a next step," she shared. "After going through this fertility journey, I have realized that there are so many other women out there who are going through fertility issues on their own, and so it's been great to kind of talk about it and have that dialogue, because it's not an easy journey."

Meghan is already a stepmother to Jim's four children from his two previous marriages. She lives half the year in St. Louis, Missouri, where Jim, 45, works as a member of their St. Louis Cardinals broadcasting crew, and half the year in Newport Beach, California, where she films The Real Housewives of Orange County.

Meghan told ET the secret to keeping their long-distance relationship strong.

"We're a lot of Facetime, a lot of selfies," she admitted. "It's difficult and we just try to do what we can do ... leaving each other notes, telling each other about our day. We have a shared calendar, and I know it sounds stupid, but it's just nice to see who he's having lunch with on a day to day basis, so we do what we can."
