NAOMI WATTS - WATTS SLAMS LEDGER OVER SCARLETT FLIRTATION

LATEST: OSCAR-nominee NAOMI WATTS reportedly called off her romance with HEATH LEDGER after becoming infuriated with his roving eye.

The 21 GRAMS beauty, 35, was deeply embarrassed when, on a recent night out, Ledger openly flirted with rising star SCARLETT JOHANSSON in front of her - leading to a humiliating argument.

Johansson, 19, was enjoying a cosy conversation with the MONSTER'S BALL hunk in a Los Angeles nightclub when Watts discovered them and reportedly dragged him back to their table.

British tabloid the SUNDAY STAR reports that Johansson simply burst into a fit of giggles following the showdown, much to Watts' disgust.
