Montag and husband Spencer Pratt are expecting their second child, due December.

The couple, who’ve been married since 2008, share four-year-old son Gunner and revealed it took “about 18 months” of trying to conceive for their second.

“I couldn’t be more excited. I don’t know who I’m the most excited for — myself or Gunner or Spencer,” Montag told Us Weekly“I just felt like something was missing. I felt like a person was missing in our family that I had this intense love for. And I kept praying about it. I’m like, if I’m not meant to have another kid — because I had accepted that at this point — I just wanted to not have that desire so strongly and I just wasn’t sure if it was going to happen or not. I just get so emotional about it.”

Montag opened up about how this pregnancy has “had more difficulties,” specifically with trouble conceiving.

“I think a lot of women struggle with this and it’s just not something a lot of people talk about because it’s so hard and it’s so personal,” the former MTV star explained. “I felt really blessed having Gunner and having such a beautiful healthy son, so I was trying not to be ungrateful for my life and for what I do have. And at the same time, it was such a deep longing in my heart that I had — wanting a sibling for Gunner and wanting to expand our family.”
