what a nice bird!!

I'm a photographer in college and i hire models from friends and friends of friends who mostly go to the same college. One of those models was an absolutely stunning girl who ill call Stacy. and she wanted to do a boudoir shoot, something I've only done twice before. so we shot some stuff and i was okay. she was okay. everything was okay. and then she asked if she could "ramp up the sexy" and i said "sure" and she..... uh.... she did. and it woke up the elephant in my pants. a lot. like. i was wearing jeans and it was super obvious. and she saw that and flipped out and called me a pervert and said she thought i was gay (I'm not. i never said that to her or anyone) and she grabbed her clothes and stormed out and told me to never contact her again. and now she's spreading around rumors that I'm a pervert and i tried to sleep with her. what should i do?
