Anyone who saw her (coolly received at the box office) film ‘Katy Perry: Part of Me‘ knows that pop diva Katy Perry was torn up by the breakdown of her marriage to funnyman Russell Brand, as evidenced by that whole sobbing backstage scene.

The indication was clear. Perry’s husband was making less of an effort to see his wife while she was on tour. Their divorce became official this week, and in a recent radio interview, Brand spoke about his love for his former wife, saying “It mostly didn’t work for practical reasons.” He also said that he wanted to have kids with her, but would not elaborate on what went wrong there since he didn’t want to make Perry sad.

He said, “I was really, really in love with her, but it was difficult to see each other … We were together when it was right to be together, and when it wasn’t we worked it out … It was a lovely relationship … It mostly didn’t work for practical reasons.”

Much of the scenario Brand detailed is depicted in the film, with a little more blame placed at his doorstep. He seemed to shift some of that blame to her career during this interview. “She’s young, successful and dedicated,” Brand said. “You can’t fully understand it until you do it. I was really into the idea of marriage and having children.”

He would not go any further when discussing domesticity, in order to protect Perry’s feelings. “I don’t want anything to hurt her,” he said. “She’s younger than me, she’s a young woman and she’s beautiful and she’s sensitive and I care about her deeply. I don’t want to be too glib. She’ll read it and she’ll be sad and I don’t want that.”

Brand  is now dating Isabella Brewster, the young sister of actress Jordana Brewster.
