Rihanna is being sued for not being a good neighbor.

On Tuesday, Christian Moeller sued the 21-year-old pop singer and Stephen Yacobian (yah-KHO’ bee-ihn), who owns the house Rihanna is renting in Los Angeles. According to the suit, Moeller, a university professor, claims the “Umbrella” singer allows cars of visitors to routinely park or wait on his property.

Moeller also claims a security camera installed at the home in the Hollywood Hills points onto his property.

He is seeking unspecified damages for trespass, invasion of privacy, and other claims.
