Carrie Underwood couldn't help but flash her huge engagement ring at the People's Choice Awards Wednesday.

The country crooner, 26, showed off the flawless yellow diamond -- worth about $150,000 -- as she walked the red carpet.

She told reporters that she worked with the ring's designer, jeweler Johnathon Arndt, before and that her fiance, hockey player Mike Fisher, picked up on that by seeing "all the little boxes in my room. He somehow managed to call him up and sneak around and make me a ring!"

How are wedding plans going?

"I bought a lot of magazines and am cutting out pictures," she told "I have a folder and I cut out pictures and glue them in. It’s in kind of a binder thing."

She said she isn't sure who she wants to design her dress, but will probably go with "someone I’ve worked with before that I know I can work well with."

She said she wants something "pretty traditional, maybe with flowers on it -- not like real flowers!"

Though she is envisioning a small wedding, "I don't see that happening," the singer said. "There are so many people. He has a huge family; they’re all really close. My family is big, but we're not that tight-knit. His is about three times the size of mine."
