Bree Olson recently retired from the Los Angeles pornography industry and signed on with a safe-sex campaign called "Get Rubber" in which she said condoms are required before she will have sex, TMZ.com noted Saturday.

Olson is one of the two young women nicknamed the "goddesses" who recently moved in with Sheen amid his highly public squabbles with his ex-wife and now-former employers at his hit series "Two and a Half Men."

TMZ said the video was available on the Internet for public parsing.
