Calm down, everyone: Rob Kardashian is NOT in rehab. A Florida-based tabloid claimed that the 28-year-old Keeping Up With the Kardashians star had checked into a 60-day program down in Palm Beach, but Kris Jenner tells E! News this is “false,” stating point blank, “Rob is not in rehab.” This, of course, isn’t the first time Rob’s found himself at the center of widely erroneous reports.
