Natalie Wood told money-hungry hubby Robert Wagner she was going to divorce him on the same night she mysteriously died in 1981, RadarOnline.com has learned.

In an exclusive interview, journalist Marti Rulli revealed Dennis Davern — the skipper of the Splendour yacht on which Wood spent her final hours — broke his silence about what truly occurred on Nov. 28, 1981.

A jealous Wagner accused Wood, 43, of cheating and smashed a bottle of wine in a fit of rage.

“Natalie’s words to him were, ‘I won’t tolerate this anymore,” said Rulli, who wrote Goodbye Natalie, Goodbye Splendour with Davern.

“Wagner had taken her to the point of no return. He had to kill her!”

The explosive revelation could finally provide investigators the missing piece — a motive — that would allow them to arrest Wagner and bring him to justice.

As Rulli noted, Wood’s decision to divorce Wagner, now 87, would have cut the fading actor out of her immense fortune.
