Carrie Underwood teased about her new song while in the studio with her son, Isaiah Fisher. According to a report from The Inquisitr  the former "American Idol" winner and new mom tweeted last April 21 about how she is "on the right track."

"Played some of the new music this morning for little Isaiah and he smiled from ear to ear the whole time! I think we're on the right track!" Carrie Underwood said about her new song.

An earlier report from UnrealityTV revealed that Carrie Underwood's new song will be about Isaiah Fisher. The baby boy was born last Feb. 27 to the country star and her NHL player husband, Mike Fisher.

"I just kind of feel a little sad 'cause all my songs are about having girls. Like, little boy baby Fisher's got nothin'!," Carrie Underwood said.

"Even 'Forever Changed,' which is one of my favorite songs, is definitely like a mother-daughter kind of a song, so... I'm gonna have to get on that."

Aside from her song for baby Isaiah Fisher, Carrie Underwood also recently introduced a new song entitled "Little Toy Guns."

According to CMT News, the Grammy winner recently explained the song.

"If you didn't pay attention to the lyrics at all, you would just think, 'Wow, this is like a cool rockin' song,' but the lyrics are actually quite serious," she said.

"The storyline is basically about a little girl who hears her parents arguing, and she - in her words - wishes that they were fake like plastic, like little toy guns and they didn't actually hurt and didn't hurt each other and didn't hurt her."

The "Jesus Take the Wheel" singer also explained the music video of "Little Toy Guns."

"I don't want to follow the story exactly. And I didn't want it to be too serious. I just really want it to be relateable," Carrie Underwood explained to the news publication.
