Mary-Kate and Ashley labelled 'The Trollsen Twins' by Peta

Mary-Kate and Ashley Olsen have been labelled "The Trollsen Twins" by PETA.

The 21-year-old stars have angered the animal rights group by continuing to wear fur and including it in their clothes lines.

PETA fumed: "Mary-Kate and Ashley have ignored pleas to stop wearing fur and are still using it in their fashion collection."

The group has now launched a campaign against "fur fiends" like Mary-Kate, who they have dubbed "Hairy Kate" and Ashley who they refer to as "Trashley".

PETA have designed a poster featuring the superstar sisters along with the tagline, "Fur Is Worn by Beautiful Animals and Ugly People".

The "Trollsen Twins" poster will be unveiled today next to their Hollywood Walk of Fame star in Los Angeles.
