Katy Perry Reveals How She Prepared To Be A Vogue Cover Girl

Katy Perry has confessed she gave up booze and coffee for THREE months before appearing on the cover of US Vogue. A fate we wouldn't wish upon our worst enemy let alone our favourite pop star.

In an interview with Jay Leno on The Tonight Show Katy spilled, "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 any alcohol for three months.

"So I was really in the zone and just really wanted to be glowing for that cover." Well Katy, it ceratinly worked. The 28-year-old was totally flawless as she graced the July cover.

However, we have to admit we're probably gonna be throwing out all hope of becoming a Vogue cover girl because, c'mon we need a cup of joe or ten two to see us through the day.
