Sources close to the situation tell us squabbles like the one this past weekend are standard for Rob and BC. We’re told this fight escalated beyond the norm because Chyna allegedly got physical with Rob right as Corey Gamble showed up to their house … and Corey had to literally rip her off Rob.
We’re told Corey called a couple of the sisters after he’d broken up the fight, and they went over to play peaceamakers, but Chyna left before they got there.
Our sources say the two are talking once again, but aren’t living under the same roof … a constant theme.
Our sources say Kim, Khloe and Kourtney are tired of Rob and Chyna’s constant off and on cycle … and Saturday’s blowup was too much to forget. We’re told they’re not taking sides either … they think both are to blame.
