Beware, meat lovers: Pamela Anderson can get foul-mouthed when it comes to non-vegetarians.

The former “Baywatch” babe called Jessica Simpson a “b—-” and “w—-” on an Australian radio station when asked about the singer. What prompted the verbal lashing? A T-shirt worn by Simpson that advertised her carnivorous ways.

Simpson was blasted by PETA in mid-June after she was photographed wearing a shirt emblazoned with the slogan, “Real girls eat meat.” Anderson, a longtime vegetarian and PETA supporter, apparently isn’t too thrilled with the tee either.

“She wasn’t referring to actual cows or chicken,” Anderson said of Simpson after spewing out her, uh, ladylike descriptions of the singer on the Kyle and Jackie O show. “She was referring to, you know, men.”

It’s worth noting that Anderson is the buxom blonde in this verbal scuffle with a world-famous sex tape who has been married (and divorced) four times. Pot, kettle - have you met?

Simpson insiders told OK! magazine that the singer’s shirt was a subtle dig at Carrie Underwood - an ex-girlfriend of Simpson’s beau, Tony Romo, who has twice been voted World’s Sexiest Vegetarian by PETA.

Simpson’s publicist had no comment Monday.
