'Dancing With The Stars: All-Stars': Pamela Anderson Gave Up Celibacy Vow, Says Show Host

Pamela Anderson said she was taking a vow of celibacy while she competes on "Dancing with the Stars: All-Stars," but according to the dance show's host, she is already "off the wagon."

"DWTS" host Tom Bergeron told "Nightline" that he recently asked the former "Baywatch" babe about her celibacy vow, which she made last month.

"I guess she thought it would give her a competitive edge," Bergeron said. "And so I happened to see her yesterday in the hall and I mentioned to her that I had been asked about her vow of celibacy and over her shoulder, with her back to me, she went, 'I'm already off the wagon.'"

A few weeks before the "Dancing with the Stars: All-Stars" premiere, which airs tonight at 8 p.m. ET on ABC, the 45-year-old Anderson told People magazine that she had "sworn off men until November," when the competition ends.

Anderson was eliminated from "Dancing with the Stars," Season 10, in May 2010 and returns tonight for the show's 15 th season, alongside Olympic gymnast Shawn Johnson, Bristol Palin and Emmitt Smith, among others.

"We've got everybody on the show who's been here before, many of whom have won it before, I'm really excited about it," Bergeron said. "I do think that each of them knows that this particular Mirror Ball trophy, however kitschy it might be, there's a certain status among fans of the show for coming into a season of all stars and walking away with that one."
