Underwood in 2010 married Fisher, a Canadian hockey player now with the Nashville Predators.

Last month, a heavily pregnant Underwood was unable to travel to Los Angeles to accept the Grammy Award for Best Country Solo Performance for her gospel-tinged Something in the Water.

Underwood, 31, is known for her healthy lifestyle and is a longtime vegetarian.

She became a vegan a couple of years ago but said that she reverted a bit during her pregnancy.

“Now I’m pregnant, it’s like, I can’t just order steamed broccoli. That’s not going to cut it,” she told CBS television’s Entertainment Tonight in December.
