Pammy and Kid Rock split?

Apparently Pamela Anderson and Kid Rock have split after 4 months of marriage. This follows reports of a miscarriage earlier in the month, and a supposed declaration from Pamela that she was desperate to have a family with her new husband adding to her 2 sons Dylan and Brandon from her marriage to Tommy Lee. But now it seems that it has all gone horribly wrong. To be fair they have always had an up and down relationship but they did seem happy - oh where did it all go wrong?
