Rock singer Pink, who has recently participated at PETA 25th anniversary gala at Paramount studios in Hollywood, has slammed Jennifer Lopez and Beyoncé Knowles for wearing fur.

Pink called Lopez "J.Bitch" and suggested that the audience should boycott anything to do with the Latin diva.

While talking about Beyoncé's curvy behind, she said: "She's got a big button - let's push hers!"

The PETA dedicated activist has previously snubbed Beyoncé for wearing fur when they came together for the UK launch of their new Pepsi advert.

Pink was outraged when she saw Beyoncé wearing a mink fur jacket over her pale blue dress.

"It's up to Beyoncé what she wears but I'm not speaking to her. I've not said anything but I think everyone knows my views - I won't ever touch fur. It's wrong.", Pink said at the time.
