The "Unconditionally" singer poses in a daring one-piece bathing suit for the magazine's February issue, and discusses the very topics included in the Love! Sex! Madness! theme.
From losing her virginity at 16 to plastic surgery to her relationship with John Mayer, Perry doesn't hold anything back in the revealing interview. MTV News rounded up the most riveting moments from Perry's GQ interview.
Praying For Boobs
Growing up in Santa Barbara, California, Perry dreamed of two things: becoming a singer and being very well-endowed. Lucky for her, both wishes were granted.
"I lay on my back one night and looked down at my feet, and I prayed to God. I said, 'God, will you please let me have boobs so big that I can't see my feet when I'm lying down?' " At age 11, "God answered my prayers," she told the mag.
"I had no clue they would fall into my armpits eventually."
Katy Is "Au Naturel"
Perry practices what she preaches. Known for inspirational songs like "Firework" and "Roar," the singer proudly revealed that she believes in her own message of self-empowerment. "I've never had any plastic surgery," she said. "Not a nose, not a chin, not a cheek, not a tit. So my messages of self-empowerment are truly coming from an au naturel product."
Not Going Up in Smoke
Katy Perry and Rihanna may be close friends, but they don't have everything in common, and one of those things is weed. Rihanna has made it no secret that she loves to puff every now and then (see her Instagram). And when her suite at November's American Music Awards was set up just a few feet from Perry's, the "Roar" singer and a GQ reporter recalled noticing a faint "cannabis sativa" smell.
"Everyone is high!" Perry declared with a giggle. She meant everyone else: "The weed — I'm not friends with it. ... I can't do that stuff. I'd be like in the corner: 'Are you trying to kill me?!' "
Question for the President
It seems like Perry has a budding relationship with President Obama. The pop star performed at a re-selection rally in Wisconsin back in 2012, and Perry told the magazine that she "might have won" the state for the democrat. Obama even called the pop star "a couple times" to show his gratitude. However, Perry's hoping to strengthen that friendship because she has a very important question to ask.
"I see everything through a spiritual lens. I believe in a lot of astrology. I believe in aliens," she said. "I look up into the stars and I imagine: How self-important are we to think that we are the only life-form? I mean, if my relationship with Obama gets any better, I'm going to ask him that question. It just hasn't been appropriate yet."
No Rush To The Altar
Perry has had her ups and downs in relationships. From losing her virginity at 16 in the front seat of a Volvo while listening to Jeff Buckley's album Grace to her tumultuous marriage to Russell Brand, which ended in divorce in 2012. But she's found love again with John Mayer, who she briefly parted ways with last year before rekindling their romance.
"I think that I needed to grow up," she revealed of the break. "I'm just having a wonderful experience with a wonderful guy. There's no rush."
