Nadine said "I think I was the least likely to be the first to have a baby, It would always come up. A couple of the other girls had wanted babies for a long time but I said no way... It was definitely a shock, but I was really, really happy. I've never felt excitement like this in my whole life. Knowing we're having a baby takes it to another level."

She told Hello! "I didn't want it to end - but the sequins, the wings and a bump wouldn't have been a good look. I loved the reunion and hopefully one day we will get back together to do something else."
