There are plenty of pressures that come with being a new parent, but country star Carrie Underwood has been stressing over something she hadn't expected.

Carrie Underwood Discusses What She Thinks Her Son Will Be Like 

"I feel like he hears me singing whether he would like that or not," said the pregnant Underwood of her baby boy during a stint on The Tonight Show Starring Jimmy Fallon on NBC Monday. "I mean, that's what I do. He doesn't have a choice in the matter."

While no fan would ever think to question Underwood's talent, lately the Something In The Water singer has felt an unusual amount of pressure to perform well, no matter where she is.

"If I'm just in my car, driving, I fell like I have to make it good because he's listening," admitted Underwood. "He's always in there…I just want to do a good job for him."

The star's little boy might want to appreciate his mother's singing while he can, especially since his father might not be the best when it comes to lullabies. "He doesn't actually know the real lyrics to any song," revealed Underwood of husband Mike Fisher, who plays in the NHL for the Nashville Predators. The singer even admitted that Fisher doesn't even know the words to her songs.

Married now for over four years, the 31-year-old singer and 34-year-old NHL player announced that they're expecting their first child together back in September. Underwood is due to give birth in the spring.

Underwood's latest album, Greatest Hits: Decade #1, was released on Tuesday.
