Carrie Underwood doesn't display her awards in her house.

The 30-year-old singer keeps her numerous trophies - including a Top Female Country Artist of the Decade Billboard Award and Best Country Solo Performance from the Grammys - in a private piano room of her home because she doesn't want to appear too self-obsessed.

Asked where she stores her many accolades, she revealed: ''I have a piano room in my house. That was one of the treats I got myself - I just wanted a fabulous piano.

''So I have plaques and things in there. I don't want them all over my house because that would be...

''People would be like, 'Boy, she likes herself doesn't she?' My husband plays hockey professionally so he's got jerseys and stuff in there too.''

The country star was offered access to private jet after her big talent show win on 'American Idol' in 2005, but she snubbed the offer because she didn't want to spiral into debt without even having made a name for herself first.

The modest singer explained in an interview with The Guardian newspaper: ''It's not like I had money of a sudden. I didn't have the money to pay taxes on a jet, so I was like, I'm good thanks.''
