Pink dons alligator costume for PETA ad

London, Feb 20 (ANI): Pop star Pink is donning an alligator costume for a new charity advert.

The 'So What!' hitmaker has been a vocal supporter of People for the Ethical Treatment of Animals (PETA), and appears in the campaign group's forthcoming cinema promo as a reptile.

The singer will be joined by British comedian Ricky Gervais - who dresses up in an equally wacky costume for the cause, reports the Daily Star.

TV funnyman Gervais confirmed the news in a blog post on his official site.

He says of their involvement: "Did a cinema charity ad for PETA. It's a great idea and I play a rabbit, and Pink plays an alligator.

"I'll post it when it's all finished and shiny."

Gervais is currently working on his next stand-up tour, 'Science'. (ANI)
