The 'Blurred Lines' singer has been married to the 37-year-old actress since 2005 and Paula says he doesn't object when she she films intimate moments with her hunky co-stars, such as with Denzel Washington in new movie '2 Guns' - and he enjoys watching the raunchy footage.
She said: ''He was like, 'I want to see everything!' He's very supportive. We've been together since high school, and we know each other's dreams.''
Paula also revealed Robin loves how tough she is in real life, and is a huge admirer of her competitive streak.
She said: ''I've always been athletic, I can hang with the guys, I get too aggressive sometimes. Once, I got a black eye playing soccer with friends. My husband was like, 'Yo dude, that's my wife'.
The couple have a three-year-old son, Julian, together and Paula revealed he wants to follow in his father's footsteps.
She told People magazine: ''He wants to be just like Daddy. He sings and makes up his own songs. One's called 'Pop Song'. It's all choruses.''
The actress thinks it would be tough to recast her character, Winifred Sanderson.
