They both lost their jobs because of racist comments they made in the Big Brother house. They both said stupid things that they are extremely dumb for saying in the Big Brother house.... The house with cameras and microphones catching your every move and word... Everyone in there signed a contract, multiple contracts one of which was a moral contract saying that CBS is not responsible for anyone losing a job (or other things going wrong for them in the outside world) because of something they do in the house. If your dumb enough to say those things, whether your trying to be funny or its an actual opinion, when you know there are people watching live feeds, then maybe you deserve to lose your job. The companies the girls worked for are smart to letting them both go because if they didn't, it would drag their name through the dirt too!
Moral of the story, when your being watched by america, don't be racist if you don't want to be called out for it and face the consequences. Sorry girls.
