Lauryn Bosstick is officially a mom of three!

The founder of The Skinny Confidential, and co-host of The Skinny Confidential Him & Her Show, 39, has welcomed her third baby with husband and Dear Media founder Michael Bosstick, a rep for the couple confirms exclusively to PEOPLE.

"Being parents and growing our family is by far our greatest joy in life. Nothing else even comes close," Bosstick tells PEOPLE. "Our baby boy arrived on June 12th to 528Hz with a full head of hair. Zaza and Townes are so excited to take care of their new baby brother. Zaza has been very tender and loving, and Townes is taking his role as big brother very seriously. It’s all been very cute to watch."

Back in January, Lauryn exclusively shared with PEOPLE that she was expecting her third baby, saying that she was "incredibly grateful" to be adding another little one to her family.

"While listening to Tim Ferriss' podcast as I was organizing my closet, I randomly took a pregnancy test!" Lauryn shared of discovering she was pregnant. "When I saw the result, I immediately went downstairs and told my daughter Zaza, who's 4, and my son Townes, who's 2."
