During an interview on Howard Stern's Sirius/XM radio show last week, Brand said their long distance relationship became too difficult. "She's young, successful and dedicated," he explained of Perry's career. "[The reality is] you can't fully understand it until you do it. I was really into the idea of marriage and having children... It was a lovely relationship ... it mostly didn't work for practical reasons ... We did work it out, she's happy, I'm happy."
