I don't use celebrity names (though Britney Spears has graced my imagination on more than one occasion). As for actual names, I base my characters on people I do actually know, and the descriptions are the same-but I only use the first name. As for where it stands-well, I wouldn't worry about the NAMES of people in stories. I think people like Britney Spears would be more offended by the porno sites she finds herself on.
