Besides Jessica, celebs like Pamela Anderson, Paul McCartney, Ricky Gervais, Kimberly Wyatt and Alicia Silverstone have urged the European Commission to uphold the cosmetics testing deadline.
The new ads are part of PETA's campaign to urge the European Commission not to bow to pressure from the cosmetics industry and postpone or compromise the 2013 deadline for banning the sale of all cosmetics containing ingredients tested on animals.
In another photograph, Jane's derriere can be seen as she carries the bunny over her shoulder and her body is reflected in a mirror.
'Don't delay the EU cosmetics test ban' - is also written on the poster.
In one of the posters, she can be seen naked lying on her back with her legs in the air along with a rabbit named Sammy on her chest. She looks seductively at the camera. The words 'No bunny should suffer for beauty' are scrawled across the poster.
Celebrity Big Brother star Jessica-Jane Clement has bared her naked body and posed with a bunny for a new PETA advertisement to prevent animal testing for beauty products.
