Robin Thicke delivered bombshell after bombshell during his recent deposition in his Marvin Gaye lawsuit: He was drunk and high during every interview he gave last year, lied to the media, and did not write 'Blurred Lines' -- Pharrell did.

Thicke, Pharrell (who produced and now, admittedly, wrote the entire hit) and T.I. are being sued by Marvin Gaye's children, who claim that 'Blurred Lines' is a rip-off of their father's smash 'Got to Give it Up.' Thicke, Pharrell, and T.I. also filed a lawsuit in order to protect their hit against such claims. Yikes.

The Hollywood Reporter has obtained Thicke and Pharrell's shocking depositions in the case. When asked to explain his comments to the media about being inspired by the Marvin Gaye song, Thicke not only swore under oath that Pharrell wrote the track -- but that he (Thicke) was also drunk and high during every interview he gave last year.

"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," he admitted.

Thicke also explained that his drug problem was the reason that he and his wife, Paula Patton, split, saying: "I told my wife the truth. That's why she left me," later admitting that he's been sober from Vicodin for many months, but not alcohol.

And as for Pharrell's writing credentials -- both artists admit that the 'Happy' singer penned the entire track, but lied about it to the media to make it appear as if Thicke co-wrote the tune.

"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 … to be more involved than I actually was by the time, nine months later, it became a huge hit and I wanted credit," Thicke explained. "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."

Pharrell agreed, but admitted he embellished Thicke's credentials because it's an every day thing in the music industry.

"This is what happens every day in our industry," Williams 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."
