Katy Perry feels like she married her celebrity crush.

The 'Firework' hitmaker - who wed British comedian Russell Brand in India in October 2010 - is now "over" her crush on 16-year-old pop star Justin Bieber because she is so in love with her husband.

She said: "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 26-year-old beauty is well known for her sexy outfits on-and-off the stage, but believes a fun-loving attitude is the most important trait to come across sexy.

Asked by Maxim magazine what makes a woman sexy, she says: "The way she presents herself and the air she has about her. You can feel her power and her confidence.

"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 cool."

Discussing her music contemporaries, Katy confesses she loves many of the women in pop at the moment.

She said: "I love what Gaga is doing, and I love what Kesha is doing. I've known Kesha forever."
