LAS ANGELES: Actress Alicia Silverstone has pal Woody Harrelson to thank for her love of getting naked.

The once-modest Batman & Robin star recently revealed she has started gardening in the nude - and it's all thanks to the former Cheers star's penchant for stripping off.

She explains, "I used to spend a lot of time with Woody Harrelson, and he's not afraid to get naked. So, around him and his wife and their kids, I just think I got more grounded.

"I was like, 'This is my body, it's not some scary thing.'"
