Mary-Kate: Heath's Death 'A Tragic Loss'

Mary-Kate Olsen is speaking for the first time about Heath Ledger's death.

In a statement to "Extra" she said, "Heath was a friend. His death is a tragic loss. My thoughts are with his family during this very difficult time."

The former "Full House" star, 21, was among the first to know about Heath's death. His masseuse called her phone four times, reportedly on speed dial on Heath's cell, upon finding him unconscious.
