Le prince but if you want the fresh prince of bel air it's le prince de bel air The expression "fresh prince" as concerns the "fresh prince of bel air" is not using the word "fresh" in any equivalent French context. (The word "frais" refers to the quality of food being recently picked - "fresh", not to be obstinate or to be very cool.) If you wanted to say "The Cool Prince", you could say "Le prince chouette" and if you wanted to say "The Obstinate Prince", you could say "Le prince obstiné".
