Girlfriend certainly did look faboosh on that cover!
It seems Katy Perry knew just what to do to get herself looking like a queen for her big debut on Vogue.
And even though some of the things she did might seem a teensy bit hard, clearly it paid off for our Katy Kat! And no, her prep had nothing to do with seksi time with John Mayer!
Katy revealed to Jay Leno that she took her Vogue cover totes seriously and went the distance to give them the best Katy she could give.
"I did a lot of my own prepping. I kind of went on a cleanse, I did a lot of stuff like vitamins and supplements, I changed my coffee to green tea, I didn't drink alcohol for three months. I was really in the zone, I just wanted to be glowing for that cover."
And glow she did! In fact, the Teenage Dream was on fire!
We're guessing she's off the strict regimen now, but it doesn't even matter. Katy still sparkles like a million diamonds!
Some are just born that way!
Ch-ch-check out more fierce pics of Katy (below)!
