The 30-year-old actress landed in hot water last year after she snuck her dogs Pistol and Boo into the country, but two charges of illegal importation were dropped after she pleaded guilty to supplying false documents and the couple made a cringe-worthy confession video apologising.

But the 52-year-old actor has joked he is going to say sorry for "not" bringing his pet pooches into a country everywhere he goes from now on.

Speaking at a press conference for his new movie 'Alice Through the Looking Glass' in a central London hotel, the 'Pirates of the Caribbean' star quipped: "I'm going to do this everywhere I go.

"I would really like to apologise for not smuggling my dogs into England. It would have been a bad thing to do."

Johnny also joked he "tried to kill" the canines in a dig at Australian Deputy Prime Minister Barnaby Joyce who threatened to euthanise the Yorkshire Terriers if Amber didn't remove them from the country, and the Hollywood actor mocked Australians for their "chipper" reaction.

He added: "The Australians are a little chipper. You know."

Amber, 30, and Johnny attended Southport Magistrate's Court in Queensland last month to hear the two charges of illegal importation had been dropped.

The blonde actress' lawyer Jeremy Kirk told the court she was under the impression Johnny's staff had dealt with the two dogs' travel forms when they arrived.

Kirk said the documents had "slipped through the cracks".

He also claimed that Amber had "nothing in it" to fill in the forms incorrectly and that it was a "terrible mistake".

He said: "It was a terrible, terrible mistake. There was no attempt to deceive."

Prosecutor Peter Callaghan admitted Amber's fame and the fact she is married to Johnny attracted attention to the case, but insisted they still have to abide by the law.

He said: "The laws apply to everyone."
