Robert Wagner considered killing love rival Warren Beatty after losing girlfriend Natalie Wood to the legendary lothario, he reportedly reveals in a new autobiography.

Wood and Beatty began a romance while shooting 1961 movie Splendor in the Grass together, leaving Wagner heartbroken and distraught. According to reports, the actor confesses hatching a plan to murder Beatty in his new book "Pieces of My Heart."

A publishing source tells the National Enquirer, "Wagner was ready to kill Beatty. He describes hanging around his house with a gun, hoping he would walk out so he could take a shot. Wracked with despair, Wagner started drinking heavily and considered suicide. He wondered if he couldn't kill Beatty, maybe he should kill himself. But an old friend pulled him out of his desolation and got him into analysis." Wagner won Wood back, but she died in 1981 after disappearing from the actor's yacht off the California coast.

The book, due to go on sale next month , also lifts the lid on Wagner's many love affairs, including romances with Elizabeth Taylor, Barbara Stanwyck and Yvonne De Carlo.
