Carrie Underwood says her best Christmas present was her fiance.

The 'American Idol' winner got betrothed to Ottawa Senators hockey player Mike Fisher shortly before Christmas Day (25.12.09) and admits the engagement was the best festive surprise she has ever had.

Writing on her fan club website, Carrie said: "I think you all know what Santa left under the tree for me this year... a fiance! Woo hoo!"

Carrie - who spent the day in her hometown of Checotah, in Oklahoma -

also received a host of presents which she was happy with.

She added: "I got a pair of pink warm fuzzy socks to keep my tootsies nice and toasty."

Despite having a wonderful Christmas, Carrie is glad it's over because she will no longer be tempted by all the delicious festive food.

The 26-year-old pop star - who is believed to be planning to tie the knot with Mike next summer - said: "I ate so much on Christmas Eve (24.12.09) that I thought I might actually get sick! But it was so good!"
