Carrie Underwood's 'challenging' marriage

Carrie Underwood admits married life has its "challenges".

The country singer married hockey player Mike Fisher last year and while she is very happy, she admits it's not always easy.

Speaking to Ellen DeGeneres on her chat show, Carrie said: "Married life is great. It comes with its own wonderfulness and challenges."

Carrie says one of the biggest problems came when Mike moved his stuff into her home after his transfer to The Nashville Predators from Canadian club Ottawa Senators.

She said: "Well, we started out you know we got married. He went back to Canada. I went back to Nashville... then he got traded to Nashville.

He came and he brought all of his c**p with him. Our house became...he's not a hoarder but he's close, maybe.

"We had it in all the guest bedrooms and he had it boxed up and stuff. He's like babe, I need more space in the closet and my heart just sinks. He'll keep like shirts and stuff and I'll go through it. You online shop, you go shopping. He loves to shop. He's going to kill me. He has stuff come in and I'm like it's not going out fast enough. If you bring stuff in and stuff needs to go out. Do we need this shirt? It has a giant stain on the sleeve. Are we going to wear this again? No, then do something with it. It's still hanging up there."

Carrie also admitted she has to "nag" her husband, but said they were learning to compromise.
