The singer/songwriter wed 25-year-old nurse Hannah Freeman on 10 October (16), and he's so convinced the couple will be together forever, he didn't see the need for a legally binding agreement to protect his assets.

Farr says a number of friends suggested that he and his now-wife sign a prenup, but he refused.

"In the music business, that's a standard,” Farr tells People, “but I said, 'If I need a prenup, I don’t need to be getting married. I’m getting married one time and that’s it!'"

“The only way this is going to end is if she leaves me," he adds, "and if she leaves me, I deserved it.”

The couple's big day was a star-studded affair with Jason Aldean serving as best man and singers Lee Brice and Colt Ford among the groomsmen.

And Farr also had a big surprise for his bride - another pal Brad Paisley performed his new single Today for the newlyweds' first dance.

"I couldn’t believe he put it together," Freeman says. "It was beautiful."
