Rick Salomon: From Pam to Cam?

Rick Salomon is moving on from Pamela Anderson to Cameron Diaz.

But it probably isn't what you're thinking.

I hear that Anderson’s estranged hubby and Paris Hilton's sex-tape costar has been cast in Diaz’s upcoming drama My Sister’s Keeper.

In the film, currently shooting in Los Angeles, Diaz stars as a former defense attorney who returns to court when she and her husband are sued by their teen daughter (Abigail Breslin) for emancipation.

No official confirmation on Salomon’s part, but a source said he plays a courtroom bailiff and does actually have some lines.

The legal experience may come in handy. Anderson ditched the divorce proceedings and filed papers earlier this month with an L.A. court to have her and Salomon’s two-month marriage annulled based on fraud.
