Mary-Kate Olsen spoke out Friday for the first time since Heath Ledger's death earlier this week. "Heath was a friend. His death is a tragic loss. My thoughts are with his family during this very difficult time," Olsen said in a statement released through her rep to PEOPLE. Olsen was one of the first people to be alerted about the actor's death, when the masseuse who discovered Ledger's body on Tuesday called the actress.
Olsen and Ledger were casually dating at the time of his death.
