Jeremy Piven's Rumored Girlfriend ARRESTED ... For Attacking Secret Husband


Jeremy Piven might be in for a big surprise -- a hot blonde Australian model whom he's rumored to have dated is MARRIED with a DAUGHTER ... and she was arrested after allegedly attacking her husband when he confronted her.

31-year-old Sophie Turner was busted March 23rd for felony domestic violence after an argument with her husband Gianmichele Gennari allegedly erupted into violence.

Gianmichele claims he confronted Sophie last month with what he called her "sexually provocative choices" ... including abandoning both him and their daughter on February 8 ... allegedly hooking up with Jeremey at a Santa Monica hotel.  She eventually came home at 3:30 AM.

Gianmichele claims Sophie often leaves the house in slutty dresses and doesn't wear her wedding ring, flaunting to the paparazzi she's single and available ... often staying out all night.

Gianmichele says Sophie responded to his complaints by attacking him ... causing facial cuts and scratches on his arm and neck.  He says she was so crazy she ripped the shirt right off his body.

Jeremy Piven has been linked to Sophie for years -- as early as 2010.  Sophie says they're just friends.   We came across a couple of video clips over the last few years that show Jeremy and Sophie awfully cozy.

Sophie's been ordered to stay 100 yards away from Gianmichele and their daughter until a court hearing later this month.

Sophie's attorney Tiffany Feder says the model maintains her innocence, adding, "Sophie has always maintained a distinction between her public persona and her private life for the benefit of her family."
