The summer of Shania Twain is upon us!

Moments before her Monday night appearance on NBC's The Voice, the country music star dropped a big ol' bombshell on the red carpet. Twain, 51, revealed to Entertainment Tonight that she's preparing to release a new album—her first in 15 years.

"I have a new single coming out in June," Twain told ET. "So I'm kicking off the summer with a new song, and then I'm finishing the summer with the release of the album. It's going to be the best summer ever for me!"

The "You're Still The One" singer acknowledged it's been a long time since she put out a studio album. Her last full-length album, Up, was released in 2002.

"I wrote the whole album myself, so it's a real statement of independence," the Grammy winner said of the upcoming album.

Although she's nervous about getting back out there, Twain said she's relieved to be finished with the project. She added that for her, songwriting is a form of "therapy."

"Creative independence is something that I haven't had in a really long time," Twain admitted. "It was really scary taking that leap. The album's done, and I feel really good. The first single is so optimistic and hopeful—regardless of how bad life could get. I really needed that message."
