The actor believes that Heard, who he got recently engaged to supports him in giving his best, reported Contactmusic.
"She's a wonderful girl. She's sharp as a tack. A southern belle and sweet as can be, and very good for me," he said.
The couple first sparked rumours they had got engaged in January after the 'Transcendence' star reportedly popped the question over the Christmas period.
Depp insists that he has left the task of wedding planning to the blonde beauty because he's "really bad" at organising things.
"I think that I would be better at making women's shoes than I would be at wedding planning, I can't plan anything. I'm really bad at that stuff," he said.
Depp and Heard first met in the sets of 'The Rum Diary' in 2011. A year later he separated from his 14-year-old partner Vanessa Paradis and started dating Heard.
