Katy Perry Praises Lady Gaga, Ke$ha In Maxim

The 'Firework' singer reveals, 'I've known Ke$ha forever. She's actually in the 'I Kissed a Girl' video.'

Everyone knows that Katy Perry is besties with Rihanna, so it might not be too surprising that Perry has only the kindest words for fellow female pop contemporaries Ke$ha and Lady Gaga, even if she has been critical of one of those women's artistic choices in the past.

"I love what Gaga is doing, and I love what Ke$ha is doing," Perry says in Maxim's new issue, for which she also serves as the cover girl. "I've known Ke$ha forever. She's actually in the 'I Kissed a Girl' video."

But, Perry isn't just dishing on her fellow lady celebrities, she's also showing some love for the fellas, one of whom she married in the fall. "I've said Justin Bieber [was my celebrity crush] quite a few times, but I think I'm over it now. I think it's probably safe to say I married my celebrity crush," the singer shares about husband Russell Brand. "Don't barf on this magazine."

Earlier this year, Perry was chosen to top Maxim's 2010 Hot 100 list, and she admits that the honor has really given her cred all over the place.

"It's a worldwide thing — the rest of the world makes it their standard," she says. "It's one of the questions they ask me in all interviews now, even in places where Maxim doesn't exist. I'll go to Timbuktu, and they'll be like, 'You're the #1 hottest,' and I'm like, 'Maxim said so, but thank you so much for saying so in Timbuktu.' "

So, what does Perry think makes ladies sexy? A fun-loving attitude, obviously.

"The way she presents herself and the air she has about her. You can feel her power and her confidence," Perry explains. "Also, the way she uses her ability to communicate, her brain and personality. I think that's really sexy because you all know the hottest woman can be the biggest bitch, and that's not cool."

Still riding high on the success of her Teenage Dream album, Perry shows no signs of slowing down, with a 2011 tour and a role in the "Smurfs" film on the way.

"You know, I wasn't allowed to watch 'Smurfs' growing up, ever. I grew up in a sheltered household, and my parents would keep us from certain things they thought were too much for us and our eyes," she recently told MTV News regarding her role as Smurfette. " 'Smurfs' had what my parents said was a lot of sorcery and magic."
