The district attorney's office said Thursday it filed one felony count against 31-year-old Nathan Lee Parada.
Parada is being held in lieu of $50,000 bail. His arraignment is expected later in the day.
Authorities say someone carrying two big knives banged on Hilton's window. She posted a photo of the Tuesday arrest on Twitter and described it as "scary."
It was not immediately clear whether Parada had an attorney.
He could face up to six years in prison if convicted.
