Carrie Underwood would never join the 'X Factor' panel because she is too loyal to 'American Idol'.

The 'Good Girl' singer shot to fame on the US pop star search show and although she has been linked to one of the vacant roles on the 'X Factor' judging panel, she insists she is ''an 'Idol' girl all the way''.

Carrie told TV show 'Extra': ''I think it's great that Simon Cowell has 'The X Factor' show, and I love seeing all of these shows giving nobodies a big opportunity. But I'm an 'Idol' girl all the way. That's the one that I love and watch. I can't see myself being a part of any another show like that.''

Carrie also revealed she and NHL player husband Mike Fisher - who she married in 2010 - are too busy for kids right now but are enjoying spending time together.

She said: ''I have my best friend around me all the time. Everybody's like, 'The first year is the hardest,' and I'm like, 'That's it? That was the hardest? Come on, you can do better than that!' It's great; he's wonderful.

''I'm good right now. As long as he's playing [hockey] and I'm doing this, it doesn't make sense. So no babies.''
