Johnny Depp has praised Angelina Jolie's "shockingly great" parenting skills.

The 'Tourist' actor admits his co-star - who raises six children, Maddox, nine, Pax, six, Zahara, five, Shiloh, four, and two-year-old twins Knox and Vivienne, with her partner Brad Pitt - does a fantastic job of juggling her mothering duties with her career, and thinks he would "probably be in prison" if he had so much to deal with.

He said: "She is such a versatile, wonderful person who can portray anything. She is a down to earth, clever, funny, woman and shockingly great mother.

"She is very calm even if she's surrounded by paparazzi. I don't know what I would do. I could've been in prison by now!"

The 47-year-old star - who has been in a relationship with French actress-and-singer Vanessa Paradis since 1998 - also joked that he "can't remember" the intimate scenes he shot with Angelina in 'The Tourist'.

When asked how he felt performing such raunchy scenes with the actress at a press conference in Tokyo, Japan, he said: "I didn't tell my family that I was shooting the film. I can't remember, I wasn't in it, I didn't take the role and this film doesn't exist. Angelina who? I can't remember her name, so I'm clean."
