"I didn't do a single interview last year without being high on both [alcohol and Vicodin]," Thicke admitted. "With all due respect, I was high and drunk every time I did an interview last year."
"When I give interviews, I tell whatever I want to say to help sell records," the 38-year-old singer added.
When asked if he considered himself an honest person, Thicke quickly replied, "No."
The deposition was conducted for the lawsuit accusing him, Pharrell Williams and T.I. of ripping "Blurred Lines" off of Marvin Gaye's 1977 hit, "Got To Give It Up."
Williams' deposition was also released on Saturday. In it, he expressed feeling "uncomfortable" multiple times when being forced to answer questions regarding his contributions to the song, as well as past comments he made about using "bluegrass chords" and "pentatonic harmonies."
At one point, the 42-year-old producer becomes so frustrated that he says, "I'm not here to teach you music." Despite the fact that he was a former coach on The Voice, Williams added that he's "not a teacher."
His anger built up even more when opposing attorney Richard Busch accused him of not being able to read music.
"I'm just asking you if you can read notes. You told me you could, and I'm asking you to identify the notes that are shown, and you can't do it can you," Busch probed. "That's because you can't actually read musical notes, can you?"
Once again, Williams let him know that he wasn't "comfortable." Shortly after, he explained, "I did not go in the studio with the intention of making anything feel like, or to sound like, Marvin Gaye."
ET previously reported that Gaye's family was awarded more than $7 million in the "Blurred Lines" trial in March. The jury found that Williams, Thicke and T.I. were guilty of infringing copyright on the song. Unhappy with the outcome, however, Thicke and Williams have sought out an appeal with help from their lawyer, Howard King.
The Gaye family originally sought $25 million in alleged damages, though the song reportedly made $16,675,690 in profits -- the biggest hit of 2013. According to court documents, $5,658,214 went to Thicke, $5,153,457 to Williams, and $704,774 to T.I. The remaining amount went to record companies Interscope, UMG Distribution and Star Trak.
Following the original verdict, the trio's reps issued a joint statement.
"While we respect the judicial process, we are extremely disappointed in the ruling made today, which sets a horrible precedent for music and creativity going forward," it read. "'Blurred Lines' was created from the heart and minds of Pharrell, Robin and T.I. and not taken from anyone or anywhere else. We are reviewing the decision, considering our options and you will hear more from us soon about this matter."
