"Blurred Lines" was a sure hit but its singer was also hit by Vicodin and alcohol at the moment of its conception.

Robin Thicke has confessed that he was high on Vicodin and alcohol during the recording of "Blurred Lines." This statement came as a defense to the accusation from Marvin Gaye's family that his hit was a rip-off of the former's song, "Got to Give Up."

In a report by TMZ, Thicke revealed that he was actually so "out of it" and that he was not creatively involved in the recording.

Thicke's responses to Gaye's lawyer were documented by USA Today. When asked about the creation of the rhythm track, the singer responded, "To be honest, that's the only part where - I was high on Vicodin and alcohol when I showed up at the studio."

He added that he wanted to get credit out of the hit. He revealed, "Pharrell had the beat and he wrote almost every single part of the song."

TMZ reported about a GQ interview wherein Thicke went excited. "Pharrell and I were in the studio and I told him that one of my favorite songs of all time was Marvin Gaye's 'Got to Give it Up.' I was like, 'Damn, we should make something like that, something with that groove,'" he said.

Williams, according to the LA Times, affirmed that the song was completed by the time Thicke finished his vocals. He is also in support of giving more credit to Thicke since it will translate to good sales.

So who's really supposed to be accused?

Thicke told the Gaye family's lawyer he does not take drugs now, and that he has been sober for two months. He finished, "When your wife leaves you, it gives you good reason to sober up."

The singer revealed issues with his ex-wife, Paula Patton saying that their separation had something to do with honesty.

The prosecutor asked if he considers himself honest. Thicke replied, "No. That's why I'm separated..." But he also said that he does not choose when to tell the truth. He argued that because of telling the truth, Patton left him.

Apparently, Thicke does not consider himself honest, but he told his wife "the truth."

Thicke's lawyer, Howard King, defended his client saying, "Robin's moment of personal vulnerability is being exploited in the hope of diverting attention from the obvious weakness of their legal claim."
