Although Queen Elizabeth II's death on Thursday, September 8, did slightly seem to bring the pair back together, "to this day, William still cannot forgive his brother," according to an exclusive source of OK!.

OK! previously reported on one of the sisters' worst instances to date, when Kim declared Kourtney one of "least exciting to look at" out of the entire Kardashian clan.
