Rihanna is suing her home's former owners.

The Bajan beauty has filed a lawsuit in Los Angeles County Superior Court claiming the previous owner of her $6.9 million Beverley Hills mansion - which she purchased in 2009 - was aware of waterproofing defects that left her property "uninhabitable" after her house was hit by a "moderate rainstorm" in January 2010.

The 23-year-old stunner claims there was serious damage to her house following the natural disaster because of defects, such as evidence of water intrusion and her balcony not having a proper slope, as well as other construction issues.

Rihanna - who is also thought to be suing Prudential California Realty and several companies that designed and inspected the abode - claims "the actual value of the property at the time of purchase, taking into consideration the extensive construction defects ... was millions of dollars less", according to documents obtained by TMZ.
