Not unless you're blood related.
It's best to keep your professional life separate from your personal life. Your Facebook friends are likely to post things on your wall from time to time which may reflect negatively on you. As the old adage goes: "Birds of a feather flock together"
Your boss may assume if these are the kind of people you are friends with then you too must be like them in many ways. Facebook should be similar to a place where you can "relax" and "let your hair down". You don't want to have to comb through your "wall" daily to make sure there are no postings or photos that could have a negative impact on your career.
