It may be her signature color, but Pink is upset about horses being painted pink for the sake of a music video. 

"If there are any animal activists around Malibu – at Leo Cabrillo State Beach, there are horses being painted for a stupid music video. Shame," Pink said on her Twitter page on Thursday.

Turns out the painted horses were being used in Selena Gomez's latest video.

"Artists should be more aware and responsible for their actions," Pink later tweeted.



But Gomez's rep says the horses were not in any danger.   

"It was important to the Production Company, Record Label and Ms. Gomez that no animals were harmed and all proper precautions were taken," Gomez's rep said in a statement to PEOPLE. "A non toxic, vegetable based powder paint was applied via an airbrush and removed with water. An official from the Humane Society was on set supervising."
