Carrie Underwood's 'Little Toy Guns' Is Based On A True Story 

The Super Bowl wasn't the only good thing Underwood had going on this week. On Jan. 31 the country star released the music video for her latest single, Little Toy Guns (featured below).

According to Taste of Country was ranked at no. 39 for February's Top 40 Country Songs and has been approaching platinum status with some killer sales.

Little Toy Guns is the second original song off Underwood's Greatest Hits: Decade #1 album, which was released on Dec. 9. Something In The Water was released as the album's first single back in September.

When she isn't wowing the NFL or climbing to the top of the charts, Underwood is preparing for the birth of her first child with husband Mike Fisher. The couple announced back in November that they are having a boy, which has prompted Fisher, who plays in the NHL for the Nashville Predators, to come up with some pretty unique names. So far Underwood has vetoed some of his more radical suggests, such as "Fly", and have discussed waiting for the child's birth to decide on the name.

Underwood is expected to give birth to her first child this spring.
