After Justin and Hailey Bieber announced their pregnancy news earlier this week, many began wondering how the famous couple were able to keep the exciting news a secret.

On Thursday, May 9, the Biebers announced they are welcoming a little one into their family, posting a video to their Instagrams from their vow renewal in Hawaii. While they were excited to share the news that they are expecting, a source tells PEOPLE that the couple wanted to keep the news private for as long as possible.

“When they found out that Hailey was pregnant, it was just the best day for them. They have both been very emotional about it,” the source says. “They feel so blessed. They’ve also felt very protective of the baby from the moment they found out.”
