Alicia Silverstone carries her son Bear Blue in between takes of filming new movie 'Gods Behaving Badly' in Central Park, New York City

"Clueless" actress Alicia Silverstone has always been into health. The 36-year-old is a vocal vegan and animal rights activist, wrote a vegan cookbook called "The Kind Diet," and currently operates a blog called The Kind Life. But it was a video she posted on her website in the spring of 2012 -- when son Bear Blu was 10 months old -- that shot her philosophies into the spotlight. The video showed Silverstone chewing a breakfast of soup and veggies and then feeding it to her son out of her mouth. "Yum! I fed Bear the mochi and a tiny bit of veggies from the soup ... from my mouth to his. It's his favorite ... and mine," she wrote along with the video. "He literally crawls across the room to attack my mouth if I'm eating. This video was taken about a month or 2 ago when he was a bit wobbly. Now he is grabbing my mouth to get the food!" The video sparked controversy over whether or not the practice -- dubbed premastication -- was hygienic, but Silverstone has defended her methods. "I can understand that it would make some people feel uncomfortable, possibly, because it's new to them," Silverstone told "Entertainment Tonight" in April 2012. "But I do want to let you know that this has been going on for thousands of years -- still going on all over the place -- and it's natural."
