Heidi Montag and Spencer Pratt are expecting their first child!

The happy couple, who rose to fame on The Hills, made the announcement on US Weekly’s Apr 24 issue; and by the looks of things, they couldn’t be happier with their imminent new arrival…

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

Heidi continued, saying that “the reality is sinking in that we are going to have a child.

“I’ve read every pregnancy book, and now I realize I don’t know anything.”

Bless her. She still has time to swat up and learn all there is to know.

Heidi can be seen getting pretty emotional during the first ultrasound in a video released by E!.

“Oh my gosh! It’s so big. I can’t believe that’s ours! That’s so exciting,” she says in the video while holding back the tears.

Aww. Anyone who has that much emotion during an ultrasound is bound to make a good mother, wouldn’t you agree?

Watch the emotional video!
