Katy Perry Talks Boobs, Russell Brand In Vanity Fair

'I don't take anything for granted,' singer says in June cover story.

It seems that every interview with [artist id="3274550"]Katy Perry[/artist] focuses on three topics: her boobs, her marriage to Russell Brand and her Evangelical childhood. She addresses all those topics once again in the June issue of

Gracing the cover in a nude-colored bodysuit, her hair cascading in front of her famous face, Perry says that while those three topics are certainly a part of her core, there's a lot more to her than just that. "I don't care what people say about my relationship; I don't care what they say about my boobs. People are buying my songs. I have a sold-out tour," she says of the California Dreams trek. "I'm getting incredible feedback from my music."

To this day, she remains hungry, noting, "I don't take anything for granted. There are 500 other girls right behind me, and I know that, because I was one of them. I remember what it's like to be someone who's always trying to get there — sending out tons of e-mails ... trying to connect with some person who could connect me with some other person. And I wouldn't be working at this pace now if I didn't truly know that fame is fleeting."

There are distractions, she says, but she has people in her life who keep her grounded. "If the core, the honesty, my story, isn't working, then all those bells and whistles aren't going to work, either," she explains. "Sometimes I can be distracted by the glamor and the fabulousness. But my husband always reminds me to keep the core intact.

"I just think I have to appreciate every day, every opportunity, work hard, and continue to evolve as an artist," she continues. "I already know my future evolution, where I'm going to go. I mean, I'm touring in f---ing Indonesia, for crying out loud."

Perry reveals that her relationship with Brand is always exciting.

"[He] never lied to me once. I trust him; there's just a level of trust that we've built up," she says of the man she married in 2010 adding that a Twitpic Brand tweeted of her in bed without makeup didn't bother her.

"We were just messing around," she said. "I didn't really care. I mean, when I go to rehearsals I look like that. I'm every woman. It takes a village to make me who I am. ... You don't have to wake up looking like, you know, Gisele [Bündchen]."
