Singer Katy Perry says she prefers men who take care of themselves which includes nails, teeth.The “Dark Horse” hitmaker shared that she likes men with trimmed hair rather than completely waxed, reports femalefirst.co.uk.“If your teeth and nails are good, you’re a candidate. If you can’t clean under your nails and you want to touch me, forget it. Personally, lesser the hair, the better. I like a trimmed man but not completely waxed,” Glamour magazine quoted Perry as saying.The 30-year-old also shared that there is a certain fragrance which always takes her back to memories of her first boyfriend.“If I meet a guy in the elevator who’s wearing ‘Acqua di Gio’, I think of my first boyfriend. One of my favourite things about fragrance is the powerful memories associated with it,” Perry said.“My signature scent now is, and always has been, a blend of vanillas. And I never spray it on my skin. I spritz and walk through—or levitate through. I like to spray it on my hair too. With ‘Mad Potion’, the two main ingredients are exotic vanilla and androgynous musk. It’s definitely a sweeter perfume. I like to be edible. I want somebody to ... eat me,” she added.
