Robert Wagner’s Marriage Explodes!

Robert Wagner’s marriage to Jill St. John has shredded under the enormous strain of the murder probe into the shocking death of his late wife, Natalie Wood, sources say.

Now insiders are saying a $25 million divorce from his “Diamonds Are Forever” wife could be a huge breakthrough for investigators — and a big problem for Wagner.
