HELP My friend is becoming a Porn Star

My best friend said she signed a deal to become a porn star. I love her dearly but I can not set there and pretend that I'm okay with it! I don't mind porn stars, I just don't want her to do it! What should I do? She says it doesn't make her a prostitute because it's legal! And she wants to lose her virginity on film! I don't want to lose her as a friend but I don't agree with her, and I'm worried about her future health and welfare.

**** I would like to clarify she just turned 18 a week ago and she claims its to get her through college. Me and her are both the same age. And I'm worried because the first time she gave a guy a bj she cried and blamed herself and then went through a depression period.
