31-year-old Underwood is expecting her first child with professional Hockey player Mike Fisher. The couple have been together since 2008 and have been married for four years. Underwood, whilst appearing on the special, also made a special announcement and revealed the gender of her child, as E! reports. She's having a boy! 

Underwood has previously described her excitement and disbelief at the prospect of becoming a parent. Underwood described the experience as 'unreal'. Speaking in September, Underwood said 'It's still kind of weird, to be honest. Sometimes I'll be with my husband, and it's like, 'I'm going be a mom. You're going be a dad. Is this real life?' But we're really excited.'
