We got BC Wednesday night heading into Project LA in Hollywood and she didn't hesitate on the issue of likeness -- Dream's a chip off the old mom block.

Rob's got a ton of recent photos of their almost 2-year-old up on social media, and her features are certainly starting to get much more defined. As for Chyna's claim ... we really can't say. Truthfully, Dream looks a little like both of them -- they each technically contributed half of themselves, after all.

How about we just stick to the custody deal in place here and call it 50/50? That ... or you can just weigh in for yourself. Either way ...
