New Couple Alert? Michelle Williams Kisses Mystery Man in Rome

Actress Michelle Williams is sparking romance rumors after she was spotted kissing a mystery man over the weekend.

DailyMail.com obtained photos of Williams holding hands with a man while taking a stroll through the Campo de' Fiori street market in Rome.

The pair was joined by her daughter Matilda, 11.

Last month, Michelle was seen enjoying a dinner with producer Kevin Walsh at Pierluigi restaurant in Rome, but a source told People magazine they have a “strictly professional relationship.”

Michelle is currently in Rome to shoot her new movie, “All the Money in the World,” which also stars Kevin Spacey and Mark Wahlberg.

Two years ago, Michelle was linked to author Jonathan Safran Foer, who wrote the well-known novels "Everything Is Illuminated" and "Extremely Loud & Incredibly Close.” At the time, a source told Us Weekly, "They knew each other through mutual friends. I'm not surprised that Michelle is attracted to him. She loves books. She reads almost every day!”
