Halle Berry
Though she's not completely opposed to Botox, Halle is against women getting injections when they are in their 20s or even younger.
She said: "I think that's something everyone needs to decide for herself.
"I'm not going to preach about whether it is good or bad. What I don't agree with is young people doing it. When I heard a girl talk about getting Botox for her bat mitzvah, I thought my head was going to blow off!"
