Spike Jonze, Catherine Keener, and Michelle Williams attend the screening of Synecdoche, New York at the 61st International Cannes Film Festival-April 2008

Michelle Williams is reportedly dating film producer Michelle Williams Spike Jonze six months after the death of ex-fiancee Heath Ledger.

The 27 year-old former Dawson’s Creek star was spotted smooching Spike, 38, outside his Lower East Side Manhattan apartment July 2.

He is the ex-husband of director Sofia Coppola.

“Michelle kissed Spike with a closed mouth on the corner of his lips,” a celebrity onlooker tells Star Magazine. “There was definitely a bit of caressing going on. She was clutching his arm. The body language was very romantic.”

The alleged couple first met when the actress auditioned for a role in Spike’s film Where The Wild Things Are. More recently, Michelle and Spike worked together on the motion picture Synecdoche, New York.
