Johnny Depp has asked a judge to reject Amber Heard's claim for spousal support.

But the 52-year-old actor - who is estimated to be worth around $400 million - is now said to have filed a response through his lawyer Laura Wasser asking for Amber's maintenance claim to be turned down.

The couple are not thought to have put a pre-nuptial agreement in place before they tied the knot in February 2015.

Amber wrote in the divorce documents that they separated on May 22 - two days after the actor's mother Betty Sue Palmer passed away.

Johnny and Amber got close after meeting in 2012 while working on 'The Rum Diary' and they tied the knot in front of just 24 people in the Bahamas last year.

Speaking of how she got "into [his] head", he previously said: "It was at the first day of press on 'The Rum Diary'. Then we married that very day!"

But they got married legally first in Los Angeles so his mother could attend.

Amber landed in hot water last year after she snuck her dogs Pistol and Boo into Australia.

She pleaded guilty to supplying false documents and the couple made a cringe-worthy confession video apologising earlier this year.

The pair attended Southport Magistrate's Court in Queensland last month, where they were last pictured in public together, 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".

This will not be Johnny's first divorce. He married make-up artist Lori Anne Allison in 1983 but they went their separate ways two years later.

He also split from French actress partner Vanessa Paradis - who he has daughter Lily-Rose, 16, and 13-year-old son Jack with - in 2012 after 14 years together.

Amber was in a three-year relationship with girlfriend Tasya van Ree until 2011.

Johnny has been doing a lot of publicity lately for his new film 'Alice Through the Looking Glass', which comes out in the US on Friday, and has been shooting the new 'Pirates of the Caribbean' film this year.
