The former reality star and fashion designer posed for the cover of People magazine with her precious blue-eyed boy.
"I always hoped I would have a boy," she told the magazine. "Boys are so fun. I was a tomboy, and I always play best with boys. When we found out, I was so excited."
The 31-year-old said that it was meeting her now-husband, William Tell, that changed her outlook on having kids.
"In my early 20s I was open to having them or not having them. But after meeting William, I changed my mind," she said. "I knew I wanted to have a family with him. But I didn't want to do it right away."
She added that it was important for them as a couple to wait several years before having children. They tied the knot in September 2014.
