Skinny Rob is back, ya'll! We previouly reported that Rob Kardashian made a vow to big sis Khloe Kardashian to shed the pounds by the time her baby girl, True Thompson  arrived and by the looks of things, he kept his word. Rob was spotted this week by paparazzi looking slimmer than he has in a very long time. 

The former KUWTK star is most likely keeping his weightloss transformation under wraps for a big televised reveal. On Khloe's season 2 of Revenge Body, perhaps? Big reveal, or not though, this bounce back is real and he deserves a shout out for his progress. 

Keep it up, Rob! We're rooting for you!!
