"We're TV actors. We're not used to performing live," Doherty toldPeople. "We do takes and we get to mess up and we know that we're going to have another take where we get to be perfect. [On Dancing with the Stars] you've got to nail it the first time perfectly. It's a lot of pressure and a lot of nerves come from a show like that. I admire people that can do that. I'm not one of them."
"Dancing with the Stars actually offered it to me the very first one that they did and I have an issue being judged -- I'm not a big fan of it," she told People. "But I love the show."
The 36-year-old actress -- whose own reality TV credits include hosting Sci Fi's Scare Tactics and Oxygen's Breaking Up with Shannen Doherty -- says she watches the show every week, according to People.
"Don't even say it, no," Garth told Access Hollywood after attending one of Ziering's Dancing with the Stars performances in April. "I can't imagine for my sake and all of America's sake, it would not be good."
Two months later, Garth's publicist confirmed that she would be part of the show's fall edition.
