WOODY Harrelson didn’t become vegan just to protect animals — there was some vanity involved. The star tells Maxim that he gave up dairy foods to help clear up his skin. “I was about 24 years old, and I had tons of acne,” he told the magazine. “I met some random girl on a bus who told me to quit dairy and all those symptoms would go away three days later.” Harrelson added, “By God, she was right.”
