The singer, Rihanna, is being sued. TMZ has put up a story regarding a lawsuit being place against Rihanna. Sources say that Christian Moeller claims the singer has been abusing and trampling his lawn. Rihanna apparently rents the house next to Moeller's. Since Rihanna moved in, Moeller claims she has been driving over his lawn to get to her driveway. He also states that not only does she drive across his lawn to get to her driveway, but she and her visitors sometime park their vehicles on the lawn. He is also suing for trespassing. Christian is a professor at UCLA for design and media art. Moeller apparently has an agreement with the owner of the house that Rihanna rents stating that part of Moeller's property can be used, but what Rihanna doing is too much. I personally think that this dude should be taking it up with the owner of the house and not Rihanna. The owner may not have made it clear where the property lines are.
