It's possible that:
* The name is incorrect: Perhaps you are thinking of a different cast member from Real World Hollywood or a different reality show.
* The person is not publicly known: It's possible that someone named Nick Brown was on the show but was not a prominent figure and did not receive widespread recognition.
* The name is fictional: You may be thinking of a character from a show or movie that shares a similar name.
To help me find the information you're looking for, please provide me with more details:
* Are you sure the show is "Real World Hollywood?" Please double-check the show title.
* Do you remember any other details about the person? For example, their physical appearance, occupation, or any significant events they were involved in on the show.
With more information, I may be able to assist you in identifying the person you're looking for.
