Carrie Underwood, ‘Good Girl’ — Sneak Peek (VIDEO)

Shhhh, don't tell Carrie Underwood's record label, but the country superstar is leaking her own new single! Well, at least a taste of it. The blond beauty shares with fans this home video (below) shot in a Nashville recording studio on what was her last day of working on her upcoming fourth studio album. The project doesn't have an official title yet, but we do know that the first single is called 'Good Girl.' And watching this video, we now know that the new tune is uptempo, sassy and bound to be a monster hit.

Carrie co-wrote 'Good Girl,' which she describes as "kick butt," with her 'Don't Forget to Remember Me' and 'All-American Girl' collaborators Chris DeStefano and Ashley Gorley. "Chris DeStefano -- I call him a little mad scientist on all of his Pro Tools stuff -- he plays every instrument you could possibly think of, and he started making this track," she recalls. "We wrote it fast, and it's just fun! It's upbeat, you stomp your feet and you can dance to it. It's got this really rockin' verse, and this really rockin' country chorus."

'Good Girl' will be released to radio this Thursday (Feb. 23). Catch a few lines of the song in the video player below.

"I am so excited to finally have new music," Carrie says. "I was lucky enough to have an amazing tour from my last album, and it feels like it's been forever, but I really had a blast writing the songs, making the music, taking my time, because I wanted it to be perfect, and I feel like we're there. So, it's very exciting for me to have new stuff to sing."

Some of the new stuff, Carrie reveals, will have a darker storyline. The full album hits stores May 1.
