Redstone marriage in trouble?

That's what Nikki Finke is reporting on Deadline Hollywood - and it might explain why she was a no-show at last week's family get-together at NY's Il Postino. And yes, this is the same Mrs. Redstone (aka Paula Fortunato) who Redstone was crazy about a couple of years back – so much so that some Viacom insiders speculated on her future ascension at the company. But sources are telling Finke that Redstone wants out of the four-year-old marriage and wants Fortunato to move out of their Beverly Park mansion (a pre-nup would only give her $1 million is the marriage breaks up). Except that she won't leave (that must make for a cheery household). Oh, and get this: the 84-year-old Redstone has been squiring around his ex-girlfriend Christine Forsyth-Peters (ex-wife of mogul Jon Peters). Why should we care about any of this? Well, it’s titillating, of course, but it also raises the $64 question about who takes over Viacom once(if) the Sumner is out of the picture.
