Dec. 18 (UPI) -- Former Real Housewives of Orange County star Gretchen Rossi is going to be a mom.
The 40-year-old television personality said in an Instagram post Monday that she's "beyond ecstatic" to be having a "miracle" baby with her longtime partner, actor Slade Smiley.
Rossi shared a photo of Smiley lifting her in his arms as she showed off a sonogram. The couple posed in front of their decked-out Christmas tree and fireplace.
"YES the News is true!!!!!!!!!!!!! We are beyond ecstatic to finally announce that we are expecting a little bundle of joy!!!!!! Our hearts are so full right now!!" Rossi captioned the post.
The Real Housewives alum thanked her doctor, Mark Surrey, and his staff for helping her conceive via in vitro fertilization after she struggled to get pregnant for several years.
"It has been a very arduous long four years of trying with plenty of heartache along the way but we remained hopeful and faithful, and thankfully God answered our prayers!" the star said.
"We are a story of hope and perseverance! Don't give up!" she urged fans. "Believe in Miracles! We feel soooo blessed to have this amazing Christmas Miracle ourselves!!! We just keep pinching ourselves! #10weeks #GodisGood #IVF @grateful."
Rossi told People she is due to give birth in July 2019. She said the IVF process has strengthened her bond with Smiley, her partner of 10 years, and made her want to share her experience with fans.
"There's been a roller coaster of emotions through this and I don't want to pretend, especially for all the couples out there going through this, it's not an easy journey -- it really is not. Yes, we have definitely grown through this, thank goodness," the star said of Smiley.
"I've decided just to be really raw and real with my videos and just show the true emotions that one goes through on this journey," she added. "I've had so many people reach out and say, 'You've helped me so much with my journey.'"
Rossi starred in Seasons 4-8 of The Real Housewives of Orange County, which completed a 13th season on Bravo this month. She has also appeared on the WE tv show Marriage Boot Camp: Reality Stars.
