"Omg @KathyHilton! That other psycho intruder just punched Cy in the back of the head as we were walking into the court house. So scary!," she tweeted, sad emoticon and all.
E! News witnessed the man as he broke through a pack of press and paparazzi and threw water at Waits' face outside the Superior Court building in Van Nuys as the couple made their way toward the court Wednesday afternoon.
The man then grabbed Waits' neck before the attacker was dragged to the ground by Hilton's security team who subdued him in a headlock.
"After the attack, they realized he is the same intruder that showed up to her home on a bicycle a few months ago. He has now been taken into custody. They are both a bit shaken up but thankful security acted quickly," the socialite's rep tells E! News. "The attacker assaulted Cy from behind.
The man, who ID'd himself as James Rainford, later told E! News that all he wanted was an autograph from Hilton and to ask her father, Rick Hilton, for permission to propose to her.
After the hearing, Paris' private security guard, Mason Burroughs, said Paris is now doing "great" after he safely escorted her out of the building.
