Country sensation Carrie Underwood is one step closer to walking down the aisle with her ice hockey star beau Mike Fisher after accepting his offer to move in together.

The "Before He Cheats" singer has been dating the Canadian sportsman for one year and went public with her feelings for the Ottawa Senators player in the liner notes of her new album, Play On.

Referring to his jersey number, she wrote, "Thank you #12. You are the most amazing addition to my life! You are such a wonderful person and have had such an amazing hand in the building of this album and in the growth of me as a person.

"I love you so much! You make my life better in every way! I thank God for you every day."

Fisher is equally as enamoured with the former "American Idol" winner and has asked her to move into his Canadian retreat.

A source tells OK! magazine, "Mike asked her to move in, and she said yes... She's on the road a lot and can't commit fully, but she did clear out space in his closet and stock his kitchen with her favourites."

And pals of the couple are not surprised if the big move leads to wedding bells: "They're completely in love. They've talked marriage. Mike's said it in front of Carrie's family. They love him and think he's great."

Underwood previously dated American football star Tony Romo.
