The 35-year-old The Hills: New Beginnings star showed off her growing baby bloat in her latest Instagram post, adding in her story that she's 15 weeks old and has baby #2.

In the photo, Heidi is wearing a long yellow floral dress as she smiles at her husband, Spencer Pratt, 38, and son Gunner Stone, 4, who are wearing a yellow dinosaur T-shirt, orange hat, and sunglasses.

"Family time! The four of us," Heidi signed the photo.

His former Hills star Brody Jenner complimented him in the comments section simply by writing "Shine." In a follow-up comment, he added a red heart emoji.

She has previously spoken candidly with her fans about her challenges as she and Spencer tried to have another child. In March, Heidi was spotted eating raw buffalo heart as part of a new diet trying to increase her chances.

"I've been trying to get pregnant for over a year and a half; I wanted to try different things," she told news. "This is a great source of nutrition!" I feel great with this diet. I have more energy, clarity, increased libido, and overall improvement in chronic pain. I am also taking a supplement called Heart and Soil's Her Pack, improving my menstrual cycle.

Last August, podcast host Speidi posted a video on YouTube that gave fans a glimpse of the time she underwent a hysteroscopic polypectomy to remove benign polyps in her uterus. On her YouTube account, Heidi said, "And I hope the surgery is successful, and that's the only reason I can't get pregnant."

"I'm hoping to get pregnant soon," she continued, adding, "Obviously, I thought it was the right time, and that's how it should be." And so thankful I didn't have any further problems or complications.
