Robin Thicke admitted he was high during most of his interviews that took place in the past year and claimed he didn’t write his hit song “Blurred Lines” in a deposition revealed in federal court on Monday.

Robin Thicke Says He Did Not Write 'Blurred Lines'

Thicke and his “Blurred Lines” collaborator Pharrell Williams gave their depositions in April with regards to a suit from the children of Marvin Gaye, who claim “Blurred Lines” is a rip-off of Gaye’s 1977 hit “Got To Give It Up.” The complaint is actually in response to a lawsuit filed by Williams and Thicke in August of 2013 to declare “noninfringement.”

In the depositions recently made public, Thicke said that it was Williams who actually wrote the entire song, without any help from the singer. When questioned about a comment made in an interview with GQ, where Thicke directly cited Marvin Gaye’s “Got To Give It Up” as the inspiration for “Blurred Lines,” Thicke said that he had actually lied in the interview. When asked why he lied, Thicke replied, “Because 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.”

Williams seemed to confirm his leading role with regards to the writing of the song in his deposition, saying he wrote the lyrics of “Blurred Lines.”

Robin Thicke Reveals Heavy Drinking, Vicodin Usage

Thicke goes on to say that he was “high on Vicodin and alcohol” when the musicians wrote and recorded the song. When pressed about interviews in which he spoke about the influence Marvin Gaye had on his music, Thicke again mentioned a drug problem, and confirmed that he was high and drunk when he appeared on Oprah.

“I did – I did say those things; however, I would like to reclarify that I was…I had a drug and alcohol problem for the year and I didn’t do a sober interview. So I don’t recall many things that I said…In fact, I was quite surprised when I read them back sometimes,” Thicke stated in his deposition.

Expanding on the nature of his drug usage, Thicke described his daily routine, saying, “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.”

When asked if he was on drugs during the deposition, Thicke said he was clean and revealed that he has been sober “for the last two months.” However, Thicke later asked to clarify his statement, saying that he has stopped taking Vicodin, but has continued to drink alcohol, though he was completely sober during the deposition.

Thicke also blamed the collapse of his marriage on his drug usage. Thicke and his wife, Paula Patton, have been separated for months amidst rumors of infidelity, but it seems it was his drug habit that caused the split. “I told my wife the truth. That’s why she left me,” he said in his deposition.
