Robin Thicke 'Blurred Lines': Admits Lying About Writing Hit - 'I was High on Vicodin & Alcohol'

Sounds like Robin Thicke's 2013 hit could well have described the state the singer was in when he recorded the song and claimed it as his.

The Hollywood Reporter, in an exclusive scoop, revealed that the 37-year-old had admitted that he didn't really write the song -- or most of it, at least. He also said he was "high" when he performed it in the studio, as he stated in a deposition he gave.

"The sworn testimony, revealed for the first time in a Los Angeles federal court on Monday, covers such subjects as authorship, song credit, drug abuse and media promotion, and almost certainly will change perceptions of a hit recording that was dubbed last year's Song of the Summer," the site noted.

Thicke and Pharrell Williams, who was also credited as the song's writer and producer, defended themselves against the estate of Marvin Gaye. The latter had complained that "Blurred Lines" was simply a rip-off of Gaye's "Got to Give It Up."

"Last week, Gaye's family filed summary motion papers and also lodged an audio mash-up of the two songs in an effort to win the case," THR reported. "A good portion of the court documents were designated as confidential, but after some back-and-forth between the parties, a judge has ordered that transcripts of the celebrities' depositions shouldn't be sealed."

And that was why Thicke and Williams' deposition managed to make it onto the news source's pages.

"I was high on vicodin and alcohol when I showed up at the studio," Thicke began, as quoted by Time. "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."

Thicke continued, "So I started kind of convincing myself that I was a little more part of it than I was and I -- because I didn't want him -- I wanted some credit for this big hit," the singer continued. "But the reality is, is that Pharrell had the beat and he wrote almost every single part of the song."

Williams had also denied he copied the 1977 classic hit.

Meanwhile, Mashable noted that Thicke had admitted he was not very honest in interviews, saying that he told "whatever I want to say to help sell records."

He also said that being dishonest and later telling the truth cost him his marriage.

"I told my wife the truth. That's why she left me," he was heard saying while being interrogated.

It could be noted that, in an interview with GQ, Thicke had revealed how he and Williams made "Blurred Lines."

"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,'" he said. "I was like, 'Damn, we should make something like that, something with that groove.' Then he started playing a little something and we literally wrote the song in about a half hour and recorded it."

Looks like he wasn't telling the whole truth in THAT particular interview.
