#9 Rihanna and Chris Brown
It seems that Chris Brown also wasn’t taught how you should behave when it comes to girls. Aside from showing some respect, you should NEVER hit them. And Brown did just that when he beat up Rihanna inside a Lamborghini. Media soon crucified him for this, but Rihanna decided to see if she could forgive him. After a while, it turned out she couldn’t and the romance came to an end.
