Rob Kardashian is 'doing very well' with his weight loss

The sock designer, who has retreated from the public eye over the last few years because of his unhappiness with his size, is working hard to get back in shape and is really "taking care of himself".

Speaking after a slimmer Rob returned to Instagram earlier this week, his friend Malika Haqq said: "Rob is doing very well. He has been working out and taking care of himself. I think Rob shares what he wants to share. I think that's how it should be for everyone. When you're ready you post, post. When you're ready to be seen, be seen. When you don't, leave him alone."
