In someone's business (4)

I believe the answer is:

nosy

(Other definitions for nosy that I've seen before include "Over-inquisitive" , "Inclined to poke into other people's affairs" , "Inquisitive in nasal manner" , "Prying, snoopy" , "Showing too much curiosity about people's affairs" .)

I've seen this clue in the LA Times.
