Melissa Lawson, a 32-year-old mother of five, is the new 'Nashville Star.' The Texas native beat fellow finalists Gabe Garcia and Shawn Mayer for the title Monday night.

Just after winning, Lawson debuted her new single, 'What If It All Goes Right.' The song will be released to country radio on Tuesday. It is also already available on iTunes. (Click here to purchase.)

Lawson's grand prize is a recording contract with Warner Brothers Nashville, with her first album to be produced by 'Nashville Star' judge, John Rich. He predicted in an interview with The Boot back in June that Lawson would be one of the "main contenders."

"Melissa is one of the best singers I've ever heard," Rich told us.

Before she hits the studio, Lawson will embark on a three-month tour with the show's Top 5 finalists.
