Bodyguards shielding Tiger Woods confronted a golf fan and accused her of being his porn star mistress, The Sun reported Wednesday.
Guards accompanying Woods on his comeback at the Masters were given photos of at least a dozen girls with links to the shamed star.
One mistook the attractive fan for X-rated actress and striptease dancer Joslyn James on Tuesday and approached her asking, "Excuse me, ma'am -- are you the stripper?"
The fan was left speechless until the guard realized his gaffe and apologized.
The miscue came as Woods, 34, played a practice round in Augusta, Ga., where the tournament will tee off Thursday.
Six armed state troopers flanked him as he was watched by massive crowds, and Woods' management team also hired their own bodyguards over concerns that one of his conquests would gatecrash the event.
James was expected to turn up after being given a black market ticket.
She also accepted an offer to appear at a strip club in nearby Atlanta -- though she was insisting Tuesday that she would not go near Augusta.
The guard who mistook the fan for her showed the photo he was issued with and said, "We've got to be extra careful."
The spectator -- who did not want to be named -- admitted she did not know whether to be flattered or insulted.
The Masters is Woods' first tournament after a five-month absence.
