F--kboys, sit down. Katy Perry is not here for you over-manicured aesthetic. In an interview with Glamour, Katy dished on her favorite scents, nail art, and the kind of grooming she likes in a man.

"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," she said. "And personally, the less hair, the better. I like a trimmed man but not completely waxed. I’m not into that f--kboy look."

Welp, now you know.

Waxed or not, if you need to figure out the best setup for a perfect Instagram shot, Katy's got you covered. One word, people: LIGHTING.

"Have the camera above you, not below you. A lot of shadows happen below, and it’s very unflattering," She explained. "Lighting is also important. Definitely be facing the light, going for the light. Catch some lighting, kids."

And for all the hairless dudes out there, know that Katy likes vanilla scents. Maybe if you smell just right and show her your best Instagram pose, she'll made an exception to her "no f--kboy" rule.
