Michelle Williams Visits Mimi O'Donnell's Apartment

Michelle Williams makes her way through the slushy sidewalks as she enters Mimi O’Donnell‘s apartment building on Wednesday afternoon (February 5) in New York City.

The 33-year-old actress paid her respects to the partner of the late Philip Seymour Hoffman, who she worked with on the 2008 movie Synecdoche, New York.

New reports have surfaced this week that Philip had tried to help Michelle‘s former partner Heath Ledger quit drugs before his umtimely death six years ago.

Joaquin Phoenix, who worked with Philip on the critically acclaimed movie The Master, stopped by the same day for a visit with his girlfriend Allie Teilz.

The results of Philip‘s autopsy were released that day, but they were inconclusive and more testing will need to be done to determine the cause of death.
