If the assignment is to find an address of a (living) famous person, it could just be a prequel to actually sending a letter to them for a writing class.
I did that in 6th grade, & sent one to the White House.
(Easiest address to find - minus the zip code which I had to look up.) lol
I don't see the harm in finding an address, but just hearing the request to find an address of someone famous is kinda sketchy without knowing why.
