Pregnancy announcements and gender reveals are a pretty big deal, so it's no wonder couples and families everywhere are trying to make them even more memorable. In the YouTube video above, an adorable family of four (the parents are expecting Baby No. 3, who they're certain is a boy) sings along to Justin Bieber's "What Do You Mean?" but with their own lyrics. Be sure to watch the entire video because after their smile-inducing song, there's footage of the actual gender-reveal party. You have to see the father's reaction when he finds out if his soon-to-be-baby is a boy or if he's having his third little girl!
