"I'm definitely not there yet, and I can't plan that far in advance," she tells January's Marie Claire, out Dec. 17, when asked about having kids. "When I decide to have a family, I'll just want to be Mom for a little bit."
The "Unconditionally" singer, 29, doesn't say whether she would consider procreating with on-again beau John Mayer, 36, but it's clear the Grammy-nominated singer is smitten.
"He's just a fantastic partner," she says. "I've been a fan of his for such a long time. He's got a brilliant, brilliant mind. It's a rad, mature relationship."
The two might not be collaborating on a baby anytime soon, but the pair did duet on "Who You Love," a song they co-wrote for Mayer's latest album, Paradise Valley. The duo released the alluring cover image of the new single last week.
Perry hints to the magazine that her reluctance to have kids stems in part from her broken marriage to Russell Brand, who she split from in late 2011 after about a year of marriage.

"I think it was a way of control. I think it was part of, 'If I have a kid, then I would have to sacrifice – I'd have to be home more.' I really wanted to, but I knew I wasn't ready for it."
It also appears her divorce was a factor in her temporary split from Mayer earlier this year, which allowed her time to heal.
"I took a break from my boyfriend, not one that I wanted," she explains. "It was like a splash of cold water to search inward on what was going on with me. That is what led me to this new awakening, this realizing, 'If I don't do some self-love, I'm not going to be able to keep the love that I want.' "
"I still needed to deal with all of my ex-husband stuff. I hadn't," she adds. "It's almost like if I kept talking about it, it would seem like I actually cared about it. I don't."
