Help please! What would you do if you had a roommate that doesn't wanna help do anything?

My cousin and I have this roommate (her friend) and she is LAZY. She doesn't do ANY of the house work and she sits around doing absolutely nothing but sit in her ass all day and watch tv on her laptop. It's irritating the hell out of us. We do all the work and when we ask her to help, she gets an attitude with us and tell us we pick fights with her. We're not! She's the one that's picking fights with us. She ALWAYS does. She asks for money and when we refuse, she calls us stingy and selfish! She hasn't been looking for a job and she's been lying about it. We had to set her straight several times and we've warned her that we're going to kick her out of she doesn't shape up. My cousin and I are the ones that make a living and working out asses off to survive. Her parents already kicked her out for her laziness. She has only been staying with us for four months. She helped out with chores but just stopped.
