Artist Robin Thicke, who is best known for his controversial hit song “Blurred Lines,” admitted to alcohol and drug abuse in a recent deposition.

Thicke and Pharrell Williams, who produced “Blurred Lines,” were deposed by Marvin Gaye’s children because of the song’s likeness to the 1977 recording of “Got To Give It Up.” During his sworn testimony in a Los Angeles federal court Monday, Thicke said he not only lied about his authorship of the song, but also that he was high during its creation.

When asked about the details of his involvement with “Blurred Lines,” Thicke confessed he was physically present, but that he didn’t have much creative input on the project. 

“To be honest, that’s the only part where – I was high on Vicodin and alcohol when I showed up at the studio. So my recollection is when we made the song, I thought I wanted – I – I wanted to be more involved than I actually was by the time, nine months later, it became a huge hit and I wanted credit.”

According to Thicke, he was simply “lucky enough to be in the room” when Williams wrote the song. Thicke’s self-admitted jealousy later drove him to take credit for the track and in subsequent interviews he repeated the false origin story.

But Thicke had trouble recalling past media comments, saying he “had a drug and alcohol problem for a year” and that he “didn’t do a sober interview.” Thicke also disclosed he was drunk and high on Norco during an interview with Oprah.

“Thicke, for his part, now claims he made all of his statements while drunk or on drugs, none of them true, and he mentioned Marvin Gaye only to sell records,” stated the counter-claimants’ court papers. “He also actually testified that he is not an honest person. This complete contempt for the judicial system, and their obligations to tell the truth, can best be summed up by Thicke’s ultimate admission, while under oath, that he ‘[does not] give a f**k’ about this litigation.”
