Here are some photos of Katy Perry at the Los Angeles premiere of Smurfs 2: Bedhead’s Descent Into Hell. Yeah, I’m so not looking forward to reviewing this one and wondering why Neil Patrick Harris has decided to do this to his career. Once again, Katy voices Smurfette, and she looks rather pretty in a Tadashi Shoji dress with Pedro Garcia shoes. I do like the dress quite a bit because the fabric drapes well and reminds me of my prom dress (that was actually a cheap knockoff of Stephanie Seymour’s “November Rain” gown), which sort of says something about Katy’s fashion taste. As always, one can tell that Katy made a huge time investment on her makeup for the evening.

Speaking of time-consuming endeavors, Katy has admitted that she took three months to prepare for her recent Vogue cover and editorial, which I imagine included time thinking about how to properly trash Russell Brand in the interview. What exactly did Katy’s preparation involve? Tons of vitamins, no coffee or alcohol (really?), and whatever else Katy thought could make her “glow.” Such measures seem like overkill since the cover was heavily Photoshopped because that’s what magazines do these days. Oh well:

It’s not easy being a Vogue cover girl! While taking to Jay Leno on Friday, July 26, Katy Perry admitted that the July issue photo spread — shot by famed photographer Annie Leibovitz — required intense preparation.

“I did a lot of my own prepping,” the “Wide Awake” singer, 28, said of the cover that was shot on a farm in Upstate New York. “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,” she continued.

Indeed, in May, John Mayer’s current girl showed off various supplements she was taking in a Twitter picture. “I’m all the about that supplement & vitamin LYFE,” she wrote with the pic.

Despite the regimen, Perry seemed pleased with the end result — sharing how “amazing” it was to work with Leibovitz. “She’s incredible,” she said. “It was really fantastic working with her … She [has] such a great vibe, she’s got no ego which is fantastic, and she really let’s [sic] me be creative as well.”

Perry, who voices Smurfette in the upcoming July 31 Smurfs 2 movie, also opened up about the vibe of her upcoming album, which she said will debut “soon.”

“I’ve had a lot of time to reflect, and I think that it will continually be what I always do — connecting to my core and trying to bring an honest message that people can relate to,” she said.

In case you missed Katy’s vitamin and supplement tweet, here’s a link to the photo that makes me believe that Katy simply poops plastic capsules. Sorry to be gross, but nobody needs that many useless pills. Talk about pouring money down the toilet. Vitamins and minerals should mostly come from food sources for best absorption, right? That’s what I’ve always read, but I do take one daily supplement that contains calcium, vitamin D, zinc, and magnesium because one can never be too careful with one’s bones. In comparison, all those baggies seem quite excessive.

Thankfully, we are not seeing photos of Katy with John Mayer on this red carpet. Instead, Katy brought her grandma as her date! We haven’t seen Grams since last year’s Billboard Awards, and this lady has spunk.
