less than a year after giving birth to twin girls, Kim Porter is reportedly leaving Puff? According to one report, she is down in Louisiana working on that new Ciara/Patti LaBelle movie, and then she’ll be moving to LA to focus on her career. It has been well-documented that Kim already receives a hefty child support for her and Diddy’s first son, Christian. (was it 25k a month? something like that) But according to one tabloid, Diddy was getting very close to actress Sienna Miller…..I’m not convinced that’s the straw that broke the camel’s back (or even that the camel’s back is even broken) but I have an inside source who will have some insight, so I’ll add to this later….
