Pharrell and Robin Thicke

Robin Thicke’s massive 2013 hit, “Blurred Lines,” is the biggest hit of his career… and now, possibly the biggest loss.

The singer, along with Pharrell Williams, lost a copyright infringement lawsuit over the song this week, which claimed it copied Marvin Gaye’s 1997 classic, “Got To Give It Up.”

According to Variety, Gaye’s family has been awarded a $7.3 million judgement in the case.

After a two-week trial, eight jurors reached a verdict in the “Blurred Lines” copyright case, determining that the infringement was not willful, but also not innocent. The jury awarded the Gaye family $4 million in damages, with profits of more than $1.6 million from Williams and more that $1.76 million from Thicke.

T.I., who is also featured on the #1 hit, was cleared of any wrongdoing.

During the trial, it was revealed that the hit song had exceeded sales of $16 million. Thicke and Williams earned over $5 million apiece for their work, while T.I. netted more than $700,000.

Both Thicke and Williams appeared in court to defend their case — both arguing that their work was original.

Thicke, who sang and played the piano, said he was intoxicated when he gave media interviews in which he talked about Gaye’s influence on the works. He also said that he was mistaken when he claimed credit for writing part of the song.
