Russell Brand feels a "responsibility" to ex-wife Katy Perry.

The British funnyman - whose divorce from the "Part of Me" singer was finalized earlier this month - says although their 14-month marriage didn't work out, he will always have loving feelings for her.

"It was right for as long as it was right and now it's right that we're not together. I feel a responsibility to her - she's living in all of this (Hollywood) and I don't want her to read things that make her think I have anything other than love for her. Because I don't want her to be hurt," the 37 year-old star said.

Russell - who married Katy in October 2010 after dating for just a year - admits marriage is "hard" and takes a lot of work: "It's really hard to be married to someone. So really the fact is, this is a person I love and I don't want to hurt her."

Russell is now said to be dating former talent agent Isabella Brewster while Katy is romancing Florence + the Machine guitarist Robert Ackroyd.
