'We're both really excited,' she told PEOPLE magazine at the time. 'We're really proud to be married to each other and to be celebrating this.'
Discussing the moment she found out that she was carrying the pair's first child, Jordin admitted: 'It was like such a shock for both of us, and then I started bawling in the closet.'
'They were shocked, scared and terrified tears, I'm going to be completely honest. I was just like, "Oh my gosh!"'
Jordin shot to fame on the US talent show American Idol at the age of just 17, and has had success with singles including No Air, Tattoo and Battlefield.
She and Dana began dating after meeting through mutual family friends and eloped in Hawaii in July of this year.
'It just more solidifies the whole team sentiment of a relationship,' she said of their wedding. 'You know you're still individuals, but at the same time everything is about "we" and "us" as opposed to "you" and "I."'
