Kristen Johnston is showing off her slimline new look by stripping for a new People for the Ethical Treatment of Animals anti-cruelty ad. The former 3rd Rock From The Sun star appears nude on horseback in a racy Lady Godiva tribute as part of PETA's bid to put New York City's carriage horses out to pasture.

The ad is aimed at tourists, heading for Central Park for the holidays, who are tempted to take a carriage ride.

Johnston will debut the ad in Central Park on Thursday, and she's not alone in her support for the cause - other celebrities who support PETA's campaign to ban horse-drawn carriages include Pink, Alec Baldwin and Chrissie Hynde.

Johnston says, "I was blown away by how these horses live, or actually I should say, don't live. The horses go from this horrible job, where they're pulling people through the streets of Manhattan all day, to this tiny jail cell in this building that's like a cramped parking garage.

"I'd say to tourists considering coming to New York, there's so much amazing stuff to do here. But please do something else. Go ice-skating, see a show, go shopping. I hope within the next year that there are no more horse-drawn carriages."

The new campaign comes as New York City council member Dan Garodnick aims to phase out horse-drawn carriages in a new bill. He proposes that eco-friendly "horseless carriages" - replicas of the classic Ford Model T - will replace the outdated horse-drawn carriages.
