What a beautiful woman!

She is a vegetarian and has been for years. Her sister Chuck is vegan. That article is from 2013. The video you're talking about with the tigers was made in 2011.

Chuck Grant, Lizzy's younger sister, became vegan in 2014. As far as I know Lana has not been a meat-eater since she became famous in 2012. I think her ethics about things like fur have improved since sis went vegan.

I think she's not: she wears fur and used tigers for a video.
