Jeri Ryan is really only known for her role as the reformed Borg fembot Seven of Nine in Star Trek: Voyager. Since the show wasn’t much more than a glorified soap opera, she was one of the primary assets in the series because she was a sexy female.
Star Trek fans from all over the world are known to stalk her at conventions, hoping that she will give them a Borg implant. They probably have a hard time choosing between her or the equally sexy Jolene Blalock (T’pol!).
