Katy Perry dissed Kim Kardashian during her recent Rolling Stones interview with her "plastic butt" and "no-man-to-have-babies" comment.

The "Dark Horse" singer told the magazine that she drew inspiration from Kim Kardashian's "plastic" butt for some of the controversial costumes she wore during her "Prism" tour.

"As far as the mummy thing, I based it on plastic surgery," she told the magazine. "Look at someone like Kim Kardashian or Ice-T's wife, Coco. Those girls aren't African-American. But it's actually a representation of our culture wanting to be plastic, and that's why there's bandages and it's mummies."

Her "no-man-to-have-babies" also didn't go unnoticed by the media and might have been yet another indirect jibe at Kardashian considering recent reports suggesting the reality star is fighting with husband Kanye West over having a second kid.

Perry said she'd rather wait for the "right time" before having a baby.

"I want to be doing that in the right time. And that's not in the next two years, you know? Maybe it's in a five-year plan, but I need to really be able to focus 100 per cent of my attention on it," she said. "I don't really want to take the child on tour. Not until, like, birth through five is over."

"I don't need a dude. It's 2014! We are living in the future; we don't need anything," she added. "I don't think I'll have to, but we'll see. I'm not anti-men. I love men. But there is an option if someone doesn't present himself."

Earlier this week, it was reported  that Kardashian and Kanye may be heading for a divorce after disagreeing over having more kids. The 33-year-old starlet and the 36-year-old rapper have allegedly hit a wall in their marriage when it comes to giving a sibling to one-year-old North West.

"Kim has made no secret for her desire to get pregnant right away with another baby," said a source close to the couple to Radar Online. "However, Kanye is resisting because he is going to be going on a worldwide tour after the release of his upcoming album. The couple doesn't even have their own house to live in! It's just too much chaos for Kanye to handle.
