Carrie Underwood says she's not working out like crazy before her upcoming wedding to Mike Fisher.

"I'm just taking care of myself, which is what I always hope to do, whether it's the ACMs or other award shows or some television appearance," the singer, 26, told reporters after winning the entertainer of the year award for the second straight year at Sunday night's Academy of Country Music Awards.

"I'm always trying to be my best. Not to look my best, but to be my best, and I'm on tour right now," continued Underwood, who rocked a Basil Soda gown to the Las Vegas show.

Besides, Fisher — who missed the show because he had a hockey game in Ottawa that night — doesn't care about her looks, she says.

"I'm not a big stresser — Mike would love me if I weighed 800 pounds," Underwood says.

At the show, Matthew McConaughey gave Underwood a pair of cowboy boots.

Last year, he joked that he "got lucky" with a pair of George Strait's boots, and Underwood later announced she wanted "to see those boots, Matthew." (She later apologized to Camila Alves, the mother of McConaughey's two kids, who was sitting in the audience.)

This year, Underwood just laughed off the boots but didn't reference the joke.
