Rob Kardashian has taken to twitter to say that his now ex-girlfriend Rita Ora cheated on him 20 times the short time they were dating. I'm not actually sure how she found the time to do anything if she slept with 20 guys while working full-time and dating Rob, but apparently she did at least according to Rob. I also find it interesting that the reports are Rita broke up with Rob, which means that Rob didn't really care he was being cheated on? Also, if you get cheated on 20 times, is that the magic number, but the first 19 are ok? Do we even care that Rob and Rita went out? Rob also says that Rita let him get her pregnant and apparently had been doing the same things with every guy she was seeing other than Rob.
