Not only did Nikki Bella, 36, and sister Brie Bella, 36, give birth to their baby boys one day apart, but the newborns practically look like twins! The former WWE champs have shared new snaps of baby Matteo and little Buddy laying side-by-side just six weeks after welcoming them into the world. “Nana visits are the absolute best!!” Nikki captioned her September 19 Instagram post, showing the newborns smiling and pulling funny faces.
