Their relationship defied the odds over the years, and now they are celebrating the next big chapter in their lives, as they have announced that they are expecting their very first child.

Congratulations, guys!

The happy couple and proud-parents-to-be made the big announcement on the cover of Us Weekly’s latest issue.

And by the sounds of it, they’ve been waiting for this moment for quite a long time…

“Heidi has wanted to be a mom since the day I met her,” Spencer said. “She has planned for and thought about this.”

“The reality is sinking in that we are going to have a child,” Heidi added. “I’ve read every pregnancy book, and now I realize I don’t know anything.”

It’s ok Heidi, there’s still plenty of time.
