Rob Kardashian -- Rolling Out and About Again (PHOTO)

Rob Kardashian -- who hasn't been seen for months -- emerged from his Calabasas home this weekend to run a few errands with friends.

It's hard to get a good look, but what you see is clear ... he looks about the same.

Rob famously went into seclusion before Kim Kardashian's wedding to Kanye West, partially due to self-image problems over his weight.

Having barely been seen or heard since, Rob did make a cameo on social media recently ... to trash his sister Kim.
