(AllHipHop News) What a difference a year makes. Last summer Robin Thicke was riding high off the success of his number one single “Blurred Lines.” This year the crooner has been constant tabloid fodder and his latest album Paula flopped.

Adding to his 2014 embarrassment, it has now been revealed that Thicke lied about taking credit for writing the biggest hit of his career.

The Hollywood Reporter obtained the transcripts from Thicke’s deposition in the lawsuit between the creators of “Blurred Lines” (Thicke, Pharrell Williams, & Clifford “T.I.” Harris) and Marvin Gaye’s family.

The Gaye’s have accused Thicke and his collaborators of stealing elements from the legendary performer’s “Got to Give It Up” for “Blurred Lines.” Thicke, Williams, and T.I. attempted to preempt a Gaye Family lawsuit by filing their own suit first.

During his testimony under oath, Thicke stated:

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. 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. But the reality is, is that Pharrell had the beat and he wrote almost every single part of the song.

These statements are different from what Thicke said about his role in the making of “Blurred Lines” in the past. He told GQ in May 2013:

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.” Then he started playing a little something and we literally wrote the song in about a half hour and recorded it.

Pharrell acknowledged during his testimony that he did write “Blurred Lines,” but gave Thicke a co-writing credit on the song because that is normal practice in the music business.

The Grammy-winning producer said:

You know, people are made to look like they have much more authorship in the situation than they actually do. So that’s where the embellishment comes in.
