Los Angeles, Apr 18 (IANS): Actress Amber Heard appeared in an Australian court after being accused of smuggling her two Yorkshire dogs, Piston and Boo, when she and her husband Johnny Depp entered the country last year.

Accompanied by the "Pirates of the Caribbean" star, she pleaded guilty to falsifying border protection documents on Monday, reports aceshowbiz.com.

Jeremy Kirk, lawyer for Heard, told the Southport Magistrate's Court on Queensland state's Gold Coast that his client never meant to lie on her incoming passenger card by failing to declare she had animals with her. He blamed jet lag for it and claimed that Heard assumed her assistants had sorted out the paperwork.

Prosecutor Peter Callaghan said ignorance and fatigue were no excuse, stressing "the laws apply to everyone."

Heard was also charged with two counts of illegally importing her two pet dogs into Australia on a private jet. However, prosecutors have dropped those two charges.

The 29-year-old actress faces up to one year in jail and a fine of more than 10,000 Australian dollars ($7,650) if found guilty for falsifying the documents.
