Talk about a red-hot mama! Hilary Duff’s infuriated mom turned the tables on a man she suspected of stalking the “Lizzie McGuire” star — pursuing him in a wild late-night chase through an L.A. suburb and cornering him for cops.

The spectacular chase occurred just days after someone tried to break into the family home through a basement window, putting Susan Duff on guard.

“Enough is enough,” Susan told The ENQUIRER. “There had been repeated incidents, and I wanted them to stop.”

In the most bizarre encounter, a guy Hilary’s mom believed was a stalker had been sitting in a parked car outside the Duff home in Toluca Lake for several hours early on August 5 when Susan’s daughter Haylie spotted the car.

With Hilary, 15, and 18-year-old Haylie in tow, Susan stormed out of the house to confront the man — but he suddenly took off.

Susan and her two children hopped in their car and chased him in red-hot pursuit through Toluca Lake for 50 minutes!

The man finally stopped at his own home, and called the police.

“Some actress is chasing me!” the guy complained, according to Susan.

The suspected stalker explained his actions to the police.

“He said he had been at our house because of his 16-year-old daughter,” Susan told The ENQUIRER.

“But his daughter wasn’t with him.”

L.A. Police Dept. spokesman Jack Richter says the man Susan chased was investigated and cleared of any wrongdoing.
