Just 11 months after Princess Sofia and Prince Carl Philip of Sweden welcomed their first child, son Alexander, they're getting ready to expand their family even more! The royal is pregnant with their second child, they confirmed in a statement on the Swedish Royal Court's website this week. "We are happy to announce that we are expecting a child, a sibling to Prince Alexander," the couple said. "We are looking forward to welcoming a new little member to our family." Sofia, who wed Philip in a stunning ceremony in June 2015, is due in September. If their newest addition is anywhere near as cute as little Alexander, we're in for a real treat.
