LOS ANGELES — A man accused of showing up at Paris Hilton's house wielding two knives has pleaded not guilty to attempted felony burglary.

Nathan Lee Parada entered the plea Friday in a Los Angeles courtroom.

He was arrested Aug. 24 outside the socialite's house and remains jailed in lieu of $50,000 bail.

Hilton was at home when Parada allegedly banged on windows. She posted a photo of his arrest on her Twitter feed and described the incident as "scary."

The heiress was arrested later in the week in Las Vegas on suspicion of carrying cocaine, which she told police was not hers.

Parada is due back in court for a preliminary hearing on Sept. 15.
