Looking happy, healthy and fit for pregnancy, Montag redefined the term “hot mommy.”

Montag frolicked in the ocean and around the Hawaiian resort with her firstborn.
Seen wearing sunglasses to match his mom’s neon swimsuit, Gunner and Montag seemed to enjoy being in the company of one another while spending quality time together.
Once a doting mother, Montag who has reached five and a half months of her pregnancy threw her hair in a ponytail and wore a protective quartz crystal around her neck as she played with her young son in the tropical paradise.

Montag and Pratt were spotted snapping photos for their own photo album memories.
Montag posed for the birthday boy taking pictures of her holding her belly.
The couple, who met and fell in love while filming the MTV reality show The Hills in 2006, married in 2008 and are still going strong fourteen years after their very public marriage.
In July, the beauty admitted she was hoping for a girl, but her son is overjoyed to have a baby brother.

Heidi added: “Growing up I always wanted guys and recently I started thinking a little bit, I don’t know, I want a bit of a girl and I have one of each.
“For Gunner, he really wants a brother, so you know, in the end I want what’s best for him and his life.”
The couple previously struggled to conceive and will be happy as long as they have a healthy child.
Spencer said, “As long as there’s a human in her belly, that’s a victory. “We haven’t worried about having a gender in my head for a long time. Thank you, God, there’s a baby here.’
The Hills star admits she started blaming herself for their fertility issues.
Heidi said, “I felt responsible.
“I felt like it was my fault… It was really hard to feel like you want something so badly and it’s just not possible… I couldn’t have done anything else.

“I felt like I was older. I might have felt a little devastated about it. I just felt like maybe I missed an opportunity, maybe I made the wrong choice.’
Heidi went to great lengths to conceive – including eating raw meat.
She previously said, “I ate bison hearts and raw meat and lots of liver. And I got an animal diet, and I’ve had all my blood done, and I’ve donated a lot of blood. By the end I was really on an animal diet, which is mostly meat, so I really eliminated most of the vegetables because they say there are oxalates and toxins that can really interfere with [pregnancy].’
The former Celebrity Big Brother star also cut most fruit from her diet and found a “great lubricant” to increase her chances of pregnancy.

She said: ‘I had minimal fruit, I actually had no grains and took a few supplements. And then I also found a lubricant that would be good for fertility. And it all came together with God’s timing and I got pregnant.”
Heidi went on to explain that leading up to discovering she was pregnant, she had in fact stopped taking pregnancy tests and was “shocked” to find out she was pregnant when her period was late.
She said: ‘I decided to stop taking pregnancy tests because every month I was so disappointed that I wasn’t pregnant. So I thought, when I was late, I’ll wait another day.
“Then I waited the next day and went down like, ‘I’m just going to take the pregnancy test.’ So I took my Clear Blue pregnancy test and I saw I was pregnant. I couldn’t even believe it. I was shocked! I cried. I ran upstairs like ‘Spencer, it says pregnant!’ Gunner said, ‘Why are you crying? What is going on?’ ‘
