Washington, Aug 14 : Sharon Stone is being sued by a man who claims he fell "down a large, concealed drop-off" while at her Los Angeles property in 2006.
Peter Krause claims that he has been fighting pain from the injury ever since.
But the 'Basic Instinct' star and her aides are baffled about the lawsuit - because they have no idea who the guy is.
"There's no record of this individual being on the property and likewise there's no record reporting this individual being injured on the property," Contactmusic quoted a rep, as telling TMZ.com.
"Neither Ms. Stone or her attorneys have seen a copy of this complaint," the rep added.
