But while some stars are still trying to find a lipstick that really stays on, others have it down to a science. Take Maxine Holloway, an adult film performer who has not only found a lipstick that doesn't budge, but has also come up with her own multi-step routine. "There are a few things you can do when applying that will help keep your pout put all night long and prevent makeout-induced clown mouth," Holloway says. "Try to exfoliate and moisturize your lips prior to application, so you have a nice smooth canvas to paint on. If I know I'll be having some kind of oral escapade, I apply my lipstick in thin layers — allowing each layer to stain and dry before the next."
