It's not too often that we get to witness the exact moment that a celeb finds out the gender of his or her unborn baby -- but 'American Idol' alum Danny Gokey proudly let fans in on the happy moment.

In a video he posted on Facebook, Gokey is heard asking his wife Leyicet, "So baby, you think it's a girl?" right before the ultrasound technician delivers the happy news: It is a girl!

"I told you!" she yells triumphantly, throwing her hands in the air. Of course, Gokey then pans the camera over to their 18-month-old son as the singer tells him that he will be the big brother of a baby sister. So sweet!

Check out the video above. Congratulations to the happy couple!
