The pop singer on Wednesday sued Prudential California Realty and several companies that designed and inspected the home.
The "S&M" singer's lawsuit claims she would not have paid $6.9 million for the home in 2009 if she had known about the problems. She claims water leaked into several rooms of the house from a balcony that lacks the proper slope and drainage after a rainstorm in early 2010. The suit states the damage left the home "uninhabitable."
She claims Landmark Design Group, which remodeled the home, has failed to make necessary repairs.
Landmark could not be reached for comment. Prudential spokeswoman Wendy Durand says the company does not comment on pending lawsuits.
