Robin Thicke has revealed that raunchy lyrics from his summer hit, Blurred Lines, were inspired by his actress wife Paula Patton.
During a candid interview on The Howard Stern Show, the 36-year-old singer admitted to turning Patton from a good girl into a bad one.
He said that the song reflects how much sexier his wife has become since they started dating as teenagers.
"The song 'Blurred Lines' has the line, 'She's a good girl, but she wants to be a bad girl,' it's very much about my wife", he told US radio DJ Stern. "My wife is Mrs. Good Girl. Gradually, over our marriage, I've turned her into a bad girl."
He also opened up about the couple's bedroom antics and wild sexscapades, revealing that he and the Mission: Impossible - Ghost Protocol star had tried almost every antic in the bedroom.
Thicke said that his other half was just as cheeky as the girls in the controversial video and 'likes it all' including spanking and bondage.
However, when asked if they had experimented with threesomes the Lost Without You singer became more coy and would not spill the beans.
"Out of respect for her, we just won't answer that one," he said before smiling.
Despite Blurred Lines climbing to the No. 1 spot in charts across the globe, Thicke has courted criticism for its allegedly "rapey" lyrics and misogynistic undertones.
In June, the accompanying video, which featured a bevy of topless models draping themselves over the fully-clothed male artistes, was banned from YouTube.
In the wake of the backlash Thicke described the song as a "feminist movement".
"When we made the song, we had nothing but the most respect for women and - my wife, I've been with the same woman since I was a teenager," Thicke told Today.
"It's supposed to stir conversation, it's supposed to make us talk about what's important and what the relationship between men and women is, but if you listen to the lyrics it says 'That man is not your maker' - it's actually a feminist movement within itself," he added.
