Carrie Underwood is to marry in a secret ceremony tomorrow.

The country singer, who has been dating Ottawa Senators ice hockey player Mike Fisher since 2008, is said to be keeping the location of the nuptials under wraps from even the guests until the very last minute.

“Carrie wants to keep the wedding small and secret. She originally wanted up to $2 million for the photo rights, but she’s now believed to have struck a deal with a weekly magazine,” said a source close to the singer.

The “Jesus, Take The Wheel” hitmaker, who got engaged to the sportsman last December, has reportedly told guests to go to an airport in a southern city in the US, where they will then be taken to the top secret site by private jet or limousine.

Carrie recently revealed she was too tied up with work commitments to put too much thought into organizing her impending wedding: “There’s a lot going on. They are still in the season. They actually only have a few more season games left. I’m touring until the end of June, and have a few shows in July, so we’re working on it here and there. We have a few things coming along.”
