Pink has slammed Selena Gomez for painting a horse fuchsia for her latest video.

The 'Stupid Girls' hitmaker - who is supporter and campaigner for PETA (People for the Ethical Treatment of Animals) - hit out at the 18-year-old singer after she was spotted filming a clip for her new video 'I Love You Like A Love Song' on a Malibu Beach with several brightly-painted creatures.

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

"Artists should be more aware and responsible for their actions.

"whether u r a fan of mine or whomEVER'S, i won't stop speaking out about animal cruelty.i've taken responsibility in the past,so should she.(sic)"

However, a representative for Selena's record company has insisted no animals were harmed during the filming of the video.

The singer's spokesperson said in a statement to People magazine: "It was important to the Production Company, Record Label and Ms. Gomez that no animals were harmed and all proper precautions were taken.

"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."
