Reports say the model, 31, and the actor, 41, had been separated for two months after she accused him of cheating on her.

In Manhattan's supreme court on Thursday, Emily filed for divorce after four years of marriage.

Reports emerged in July that the film producer, with whom Emily shares a 16-month-old son named Sylvester Apollo Bear, was a "serial" cheat

which led to the initial breakup between Emily and Sebastian.

People magazine reported in July that a model insider revealed the couple had broken up and that Emily was now concentrating on being a mother.

The insider was quoted saying: “They split recently. It was Em’s decision. She is doing OK.

“She is strong and focused on her son. She loves being a mum.”

Emily and Sebastian haven't talked about the state of their relationship in public yet.

The last time they were seen together was in mid-June when they were on vacation in Italy.
