Billionaire Donald Sterling is taking legal action against celebrity website TMZ and an ex-girlfriend over the recording of his off-color remarks that cost him ownership of the Los Angeles Clippers.

Sterling's lawsuit filed in Los Angeles Superior Court accuses TMZ and V. Stiviano of violating his privacy and causing damage on a "scale of unparalleled and unprecedented magnitude."

The suit is the latest salvo in a legal soap opera that began in April 2014 after the recording caused a firestorm of criticism when the real estate baron was heard whining to Stiviano that she shouldn't associate with black people.
