Pamela Anderson Refuses Ice Bucket Challenge, Kristen Stewart & Nicholas Hoult Accept

iStock/Thinkstock(LOS ANGELES) -- One celebrity who’s not taking the ALS Ice Bucket Challenge? Pamela Anderson. The Baywatch actress and staunch animal rights activist said she will not be taking part in the challenge because of the ALS Association’s use of animal testing in its research.

“I enjoy a good dare -- it’s always good to bring awareness -- in fun, creative ways. I don’t want to take away from that, but it had me thinking,” she wrote on Facebook. “Digging a bit deeper I found that we may not be aligned in our messages. So…I thought instead, I’d challenge ALS to stop animal testing.”

She also posted a picture of herself holding a piece of paper with “Stop Animal Testing” written on it.

Meanwhile, Kristen Stewart and Nicholas Hoult were more than game for the challenge. They did make sure to conserve water, though.

Stewart and Hoult, who co-star in the upcoming film Equals, dunked their heads in buckets of water along with pal Scott Fahrendorf. "In good faith you must believe this was all done with dirty bath water,” Stewart said. “Please be considerate of California water conservation."

Stewart had been nominated for the challenge by Anne Hathaway. Stewart, who recently appeared in the “Just One of the Guys” music video for Jenny Lewis, nominated the singer along with her video co-star Brie Larson. She also nominated fellow Equals co-stars Jacki Weaver and Max Thieriot.

Hoult -- a.k.a. Jennifer Lawrence's ex -- nominated his A Single Man co-star Colin Firth, his Kill Your Friends co-star Craig Roberts, and his Skins co-star Joe Dempsie.

As of Thursday, the Ice Bucket Challenge had raised 41.8 million dollars for the ALS Association over the past three-plus weeks.
