If CB has been messaging on there as i believe that is true, because he asked that the "Find Lonzie" page be removed when things were getting a bit heated over there a while back, and whoever owns the page changed its name to "Missing Children in Florida", so as to not make it specifically about Lonzie only, then the recent couple of messages under his name, one of them by LL, then he would of read those other messages by RB about being the real dad. No one CB or LL disputed that there, so its anyone's guess really.
IMO not everyone that posts on SM is making up rumours, a lot of stuff on various people's pages is factual i would think, but i know on here it is considered as rumour in certain instances. Apparently RB has informed LE of certain things, so it may or may not come out eventually if true.
