Katy Perry has no regrets about her failed marriage to Russell Brand.

In the latest issue of The Hollywood Reporter, the 27-year-old singer opened up about her divorce from the British comedian –- and revealed a post-split outlook as sunny as her hit pop songs.

"I still believe in love and marriage. I've just learned lessons along the way. I regret nothing," the songstress told the magazine.

The issue also confirms that Perry's new concert-doc "Part of Me" (opening July 5) includes some backstage footage of Perry and Brand, who divorced in February 2012 after 14 months of marriage.

It seems the former couple is on the same page about their split. In May, Brand expressed a similar sentiment about the failed relationship to Ellen DeGeneres. "I still love [Perry] as a human being, but sometimes when you're in a relationship, I suppose it doesn't work out, does it?" he said. "That doesn't mean I regret it or anything."
