Damn, Rob! Poor guy. Working his butt off to lose all the weight he’s gained since his break up with Rita Ora. Last time, we peeped him cuddled up, hugging another girl during his work out – so he’s not doing that bad. But in these pics, it’s apparent he gained a massive amount of weight. But he is trying to do something about it, working out so much he can barely catch a breath! Oh, and he’s wearing socks from his sock line. Maybe his choice is socks are why Rita left him! See the photos of him, his work out and socks below!
