Kutcher allegedly saw two photographers sitting in a car outside his house Saturday night and lunged into the vehicle and began ripping the shirt off one, "Extra" reported Monday.
The second cameraman reportedly caught the entire incident on film.
Once he realized he was being filmed, Kutcher reportedly backed off the attack and made amends.
The photographers did not call authorities.
Kutcher and gal pal Demi Moore have repeatedly denied Hollywood rumors that she is pregnant with his child.
