Carrie Underwood Plans Stress-Free Wedding

Carrie Underwood's upcoming marriage to Ottawa Senators hockey player Mike Fisher is being given glowing advance reviews by her fellow country singing buddies.

Dierks Bentley, who has toured with Carrie and who also happens to be a big hockey fan, tells PEOPLE magazine why he thinks Carrie and Mike are going to make a great team. "They are really cute together," Dierks said at Clive Davis' pre-Grammy gala over the weekend. "They seem pretty devoted to each other, and they come from a good background ... so I think that's the key to a good marriage."

Miranda Lambert -- who makes no bones about her love of down-home country life versus city life -- thinks Carrie will make a good wife, mainly because she's grounded. "Carrie is very down to earth and stable," says Miranda. "She's a great girl ... she really is. I'm happy for her."

As for the bride-to-be, Carrie says she just wants to enjoy her wedding day and not obsess over the planning. "We have some of the big decisions made," she tells PEOPLE. "I don't care about details. I just want to show up and have a good time!"

To ensure that fun trumps stress on her big day, Carrie is leaning on her wedding planner. "Any spare moment is definitely used to talk about wedding stuff," she tells ETOnline. "We've got a great planner, and we e-mail back and forth, and we talk. We're going to be visiting some places at some point, and figure out where we're going to have it."

Last Sunday, Carrie took home a Grammy for Best Country Collaboration With Vocals for 'I Told You So,' with Randy Travis. Next Sunday, she will sing the National Anthem as part of Super Bowl XLIV pre-game festivities at Sun Life Stadium in South Florida. Her performance will be televised live on CBS Sports, prior to kickoff.
