After forking out $6.9 million on a mansion, you would expect a property of that calibre (and price tag!) to be in tip-top condition … but it seems that this is not the case for Rihanna!

The pop starlet filed a lawsuit in L.A. County Superior Court on Wednesday and is suing the former owner of her Beverly Hills mansion, and the real estate agent along with the property inspector, for allegedly lying about major property defects.

According to the docs, Rihanna’s home was hit by a “moderate rainstorm” in January 2010 … but because of the defects, water leaked into multiple rooms. ausing some serious damage.

Rihanna claims she got screwed — because “the actual value of the property at the time of purchase, taking into consideration the extensive construction defects … was millions of dollars less” than the price she paid for it.

After spending that amount of money, we’d sue too!
