It was 10 years ago when Carrie Underwood first popped up on baker Ivey Childers’ radar, all thanks to a hair stylist.

Childers and one of Underwood’s label reps shared the same “hair lady,” so when the time came to serve up a bangin’ birthday cake for newly-crowned American Idol, Childers was the lucky one to get the call.

But, the two didn’t actually meet until a few years later when the culinary whiz began dating Underwood’s music director/bass player, Mark Childers. An instant bond was born, and now the gals are peas in a pod.

Childers designed Underwood’s spectacular cupcake tower for her wedding to hockey star Mike Fisher, so it was only appropriate that Underwood and Fisher return the favor to celebrate one of Childers’ biggest milestones: the expected arrival of a beautiful baby girl.

Recently, Fisher and Underwood threw quite the unconventional shower in honor of Childers and her little one at exclusive hot-spot Citizen, in the trendy Gulch area of Nashville. Friends and family enjoyed cocktails, karaoke, a photo booth with hilarious masks and props and even one of IveyCake’s own massive cupcake towers with a topper bearing the baby girl’s name, Leona.
