Thicke admitted under oath that he was "high on Vicodin and alcohol" when he showed up to record his hit single "Blurred Lines" and that he "didn't do a sober interview" for the entire year that he was promoting his 2013 album of the same name.
"Every day I woke up, I would take a Vicodin to start the day and then I would fill up a water bottle with vodka and drink it before and during my interviews," he said. "I don't recall many things that I said. In fact, I was quite surprised when I read them back sometimes."
Thicke is currently embattled in a legal dispute with the children of Marvin Gaye, who filed a lawsuit that accuses Thicke, Pharrell Williams and Clifford "T.I." Harris Jr. of copying their father's 1977 hit "Got to Give It Up." The singer's sworn testimony was previously being held confidential, but was revealed on Monday for the first time in a Los Angeles federal court.
UPDATE: Thicke's lawyer, Howard King, attorney and managing partner of King, Holmes, Paterno & Berliner, issued the following statement on the singer's behalf: "Robin's moment of personal vulnerability is being exploited in the hope of diverting attention from the obvious weakness of their legal claim."
Thicke had said in past interviews that it was his intention to draw inspiration from Gaye with his new music. Now, he's singing a different tune.
"I lied in my story so I could at least make it seem like, 'Hey, I'm the guy who came up with this great idea,'" he said. "And you know what? I didn't even use the Marvin Gaye thing until everyone started saying to me, 'Hey, it's reminiscent of the Marvin Gaye song.' And I was like, 'Well, yeah, that was my idea. I wanted to do something like that.' There was no other way for me to get credit for the biggest song of the year unless it was my idea."
Thicke also copped to lying about just how involved he was in the creation of the track.
"After making six albums that I wrote and produced myself, the biggest hit of my career was written and produced by somebody else and I was jealous and I wanted some of the credit," he said. "The reality is, is that Pharrell had the beat and he wrote almost every single part of the song."
Pharrell's April deposition was also released on Monday. In it, he says that the 2013 song of summer was his creation, but that "It wouldn't be what it was -- what it is today" without Thicke's vocals.
Asked early in the deposition whether he considers himself an "honest person," Thicke said, "No. That's why I'm separated." Later, he was asked if he's selective about when to tell the truth.
"Absolutely not," he replied. "I told my wife the truth. That's why she left me."
Thicke said in April that he had been sober for the past two months, but that he continued to drink alcohol. "My sobriety of is off Vicodin," he said at the time. "When your wife leaves you, it gives you good reason to sober up."
Thicke went on to release his Blurred Lines follow-up album, Paula, dedicated to Patton, in July. The album didn't fare as well as its predecessor, selling only 24,000 copies in its first week -- an 86 percent drop-off from Blurred Lines' debut.
