Carrie Underwood admits marriage challenge

Carrie Underwood has said that married life comes with "its own wonderfulness and challenges".

The 'Undo It' singer, who married hockey player Mike Fisher last year, told The Ellen DeGeneres Show that she is still adjusting to living under the same roof as her husband following his transfer to Nashville.

"He got traded to Nashville and came and brought all his crap with him, so our house became… he's not a hoarder but he's close, maybe," she said.

The country star, who performed with Steven Tyler at last weekend's ACM Awards, went on to say that one thing her husband refuses to part with is shirts, revealing that he likes to shop online but never throws out his old items when the new purchases arrive.

"He has stuff come in and I'm like, 'It's not going out fast enough. If you bring stuff in, stuff has to go out. Do we need this shirt? It has a giant stain on the sleeve? Are we going to wear this again? No? So do something with it!'"

Fisher had been playing for the Ottawa Senators when the couple married in July 2010, but was transferred to the Nashville Predators earlier this year.

Underwood can be seen in the upcoming movie Soul Surfer, which is based on the true life story of teenage surfer Bethany Hamilton, who lost her arm in a shark attack.

Underwood's full interview with Ellen airs today.
