Alicia Silverstone, star of the movie Clueless, was recently videoed feeding her baby boy like a bird, landing her on the list of trending topics on Twitter.

The video of Silverstone feeding her 11-month-old son Bear Blu was posted on YouTube on March 20. It shows her chewing the food and then passing it onto her son directly from her mouth.

The actress also posted the video on her site, The Kind Life.

I just had a delicious breakfast of miso soup, collards and radish steamed and drizzled with flax oil, cast iron mochi with nori wrapped outside, and some grated daikon. Yum she wrote. 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.

He literally crawls across the room to attack my mouth if I'm eating, her post read. 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!

But the video has since attracted much attention, with some Youtube commenters saying, That is really disgusting, and not cute what-so-ever.?

Another has described it as vegan hippie nonsense, adding I hope you give your kid some b-12 vitamins because he will need them if all u feed him if vegan stuff.
