Gretchen Rossi Pregnant?

Ready for this? Gretchen Rossi is nearly halfway through her pregnancy already! The Real Housewives of Orange County alum recently explained to her followers that she doesn't have "much of a belly yet" because she's both naturally fit and a first-time mom. But Gretchen's little bun is starting to show more and more every day, so the mama-to-be recently offered a peek at her bare bump.

How to Watch

Watch The Real Housewives of Orange County on Thursdays at 9/8c and next day on Peacock. Catch up on the Bravo App.

Gretchen's post showed photos from her sixteenth week of pregnancy, when her baby was about the size of a nectarine. In the photo, Gretchen was wearing nothing but a pink Calvin Klein bra and underwear set. With a glowing tan, she let her sun-streaked hair hang down over her shoulder.

"This whole growing a baby inside of me has been the most amazing thing I have ever experienced! My body is changing and definitely expanding but I am taking it all in stride and enjoying every minute of it!" she noted.

I didnât get a chance to post this pic from a of couple weeks ago, but here is a pic of my little baby bump! As you can see I donât have much of a bump yet, but when I take it from different angles it shows a little more (like in pic #3) I am #18 weeks today so need to take another pic because my belly has definitely grown some! ðð»â¤ï¸ ââââââââââââââââââââââââ-Enjoying my second trimester so much better! Finally feeling like a human again and have more energy! Weeks 14-17 have been a lot better for me, thank goodness! Two days ago I started to feel a little heaviness in my lower abdomen which is a weird sensation for me, but Doc said itâs cause my uterus is expanding and the baby is sitting right between my pelvic and bottom of my belly button â¤ï¸ Soo crazy! ââââââââââââââââââââââââ-This whole growing a baby inside of me has been the most amazing thing I have ever experienced! My body is changing and definitely expanding but I am taking it all in stride and enjoying every minute of it! Just so very grateful for our little one on the way! Doing a Gender Reveal Party here very soon! So stay tuned! ðð»

Now, we can't help but notice that the Orange County alum was wearing a pale pink bra-and-underwear set, but this isn't her gender reveal quite yet! In her caption, Gretchen noted that she'd be sharing the sex of her little one "very soon."
