Girlfriend certainly did look faboosh on that cover!
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!
