We can't believe he's managed to stay hidden for so many months!

Rob Kardashian had reportedly checked into rehab in Florida this month, but that's definitely not the case, as we caught the reclusive reality star driving around his Calabasas neighborhood in a white Range Rover yesterday. Although it was tough to get a good look at him, it appears he is still quite hefty and has grown a mustache.

The last time we saw the former DWTS pro was way back in March! Multiple media outlets were reporting that Kimmy K's brother had finally decided to seek help at an undisclosed facility, but momager Kris Jenner dismissed the chatter as pure nonsense. "Completely fabricated," the family matriarch told ET.

He has struggled with massive weight gain, depression, and alleged substance abuse for some time, so we would advise him to stop chilling at his sisters house and get his life back on track!
