Remember THIS Rob K? And that Phatty?

Over the past couple years he’s battled weight issues, gaining nearly 100 lbs.  Despite his efforts to stay out of the spotlight, the paps still managed to snap photos here and there.

Now, Rob may very well be on his way back.  He recently posted an Instagram pic revealing a considerable weight loss.

Memories…We may be able to enjoy that phatty once more…
