The only way Brandi will return is if LVP quits (and she never will). Lisa's said numerous times that she wants nothing to do with Brandi and wouldn't film with her again. Also Brandi hinted a few months ago that LVP sued her, which could've also been a reason why Brandi wasn't asked back. I haven't read the book, but I heard Andy put in his book that Brandi was fired because she got physical with Kyle (?!?!). And also that none of the ladies apart from Yolanda agreed to film with her. So I highly doubt that Brandi will ever return to BH, Jacqueline is more likely to go back to NJ at some point though.
