If you are a true So You Think You Can Dance 2012 fan, you know that hip-hop choreographers Tabitha and Napoleon D’umo were very much pregnant and looking like Tabitha was about to deliver that baby right on the show. Nigel Lythgoe even joked on one of the performance shows for So You Think You Can Dance Season 9 that she needed to keep the baby in during the show. Well, it looks like Nappytabs has popped and they welcomed their new son, London Riley, last night!
