Robert Kardashian gained 18 kg when Rita Ora dumped him!

Rob Kardashian and Rita Ora broke up in december 2012, and now he has for the first time spoken out about their time together - and how he became a total wreck when they broke up. "All I did was waste a lot of money and gaining 18 kilograms," said Rob to their sisters in the latest episode of Kourtney & Kim Take Miami. "I need to focus on me. This is what it's all about now," he continued.

"Rob came from a very strange relationship. They were actually together for almost a year but Rob never admit they were a couple in real life," explained Khloe Kardashian facing cameras. "Because she (Rita Ora) is in the entertainment business, she wanted to appear to the world as a single girl. I think Rob got really depressed of their relationship."
