“X-Men” star Hugh Jackman was a Hamptons hero Sunday at the Southampton Village farmers market. Jackman noticed vendor Donna McCue having trouble setting up the stand for her Fat Ass Fudge Company on the cold, blustery day, and, “He very kindly helped set up the tent in the wind and even posed for pictures afterward,” a spy said. Bearded Jackman then bought some fudge and power bars from McCue, who at first didn’t recognize the star, and he joked, “You know I get $7.50 an hour.”
