The billboard comes days after Davidson allegedly left an explicit voicemail for Daphna Nachminovitch, the senior vice president of PETA's Cruelty Investigations Department, on Monday. Nachminovitch had called out the "Saturday Night Live" star for purchasing a dog instead of adopting.

"Thank you so much for making comments publicly that I didn't adopt a dog," Davidson said in the voicemail. "I just want to let you know I'm severely allergic to dogs, so I have to get a specific breed. I'm only not allergic to Cavapoos, and those type of dogs."

"And my mom's f---ing dog, who's two years old, died a week prior, and we're all so sad. So I had to get a specific dog. So why don't you do your research before f---ing create[ing] news story for people because you're a boring, tired c---. F--- you. And suck my d---."
