Robin Thicke previously admitted to being high on drugs and alcohol last year, but new unsealed videos of the singer's "Blurred Lines" deposition shows him discussing those issues with Richard Busch, an attorney for Marvin Gaye's estate. Wearing a black T-shirt and looking a little bored with the line of questioning, Thicke revealed he didn't do a single interview sober last year.

In one clip posted by the Hollywood Reporter, Thicke said he lied to the media during interviews because he wanted to help boost album sales.

"When I give interviews, I tell whatever I want to say to help sell records," Thicke said. He later added, "With all due respect, I was high and drunk every time I did an interview last year."

The 38-year-old singer, who was being questioned in regard to the plagiarism case brought against himself and Pharrell Williams by Gaye's children, also admitted in another video that he frequently used Vicodin.

"I didn't do a single interview last year without being high on [alcohol and Vicodin],” Thicke confessed.

When asked by Busch whether he was an honest person, Thicke quickly responded, "No."

Gaye's family sued Thicke, Williams and rapper T.I. over the 2013 song, "Blurred Lines," claiming in its lawsuit that the defendants used elements of Gaye's 1977 song, "Got to Give It Up," without permission.

Both Thicke and Williams denied ripping off Gaye's song, but in March a jury sided with the now-deceased singer's family and awarded the estate $7.3 million. A judge later cut that figure to $5.4 million.
