Lawyer For Mary-Kate Olsen: She Knows Jack

After reports surfaced the FBI is repeatedly trying and failing to get Mary-Kate Olsen to spill it about how Heath Ledger got the drugs that killed him, the skinny one's attorney, Michael Miller, has issued this statement:

"Despite tabloid speculation, Mary-Kate Olsen had nothing whatsoever to do with the drugs found in Heath Ledger's home or his body, and she does not know where he obtained them. Regarding the government's investigation, at Ms. Olsen's request, we have provided the government with relevant information including facts in the chronology of events surrounding Mr. Ledger's death and the fact that Ms. Olsen does not know the source of the drugs Mr. Ledger consumed."

Brittle Mary-Kate Olsen is at the center of the Heath Ledger investigation.

Cops say the masseuse who found a dead Heath Ledger last January spent nine minutes making three separate calls to Olsen before calling 911.

He then called her again after paramedics arrived. After getting the calls, cops say Mary-Kate sent her bodyguard to go check on the situation.

What does she know and why is she being all shady? If she keeps stonewalling the feds, Mary-Kate will have worse enemies than Spencer Pratt.
