Washington, Dec 12 (ANI): 'Full House' stars Mary-Kate and Ashley Olsen are back in the news for all the wrong reasons.

The twins have been attacked by PETA for wearing fur.

In a new ad campaign, which was unveiled on Dec 12 at the Olsens' Walk of Fame star on Hollywood Boulevard, People for Ethical Treatment of Animals (PETA) has dubbed the 21-year-olds 'Trollsen Twins' for wearing animal fur.

The ad features the twins above the headline "Fur Is Worn by Beautiful Animals and Ugly People."

"Thin-twins Mary-Kate and Ashley Olsen are about to get some publicity that will have them running away faster than if they'd spotted a calorie," Us magazine quoted PETA, as saying.

To coincide with the ad, PETA has also launched a new web site devoted to "Hairy-Kate" and "Trashley."

It features, among other things, a mash-up video entitled "Full House of Horrors."

In the video, footage from the twins' former hit TV show is interspersed with scenes of animals being killed for fur.

"No one would argue that Mary-Kate and Ashley could use some meat on their bones, but the last thing they need is hair on their backs," PETA's Assistant Director of Youth Campaigns Dan Shannon said in a statement. (ANI)
