Robin Thicke has been a man of many words, and dance moves, this summer promoting his hit song "Blurred Lines," but he needed only one word to respond to accusations that the song is uncannily similar to one by the late Motown legend Marvin Gaye.

"No," Thicke, 36, said Thursday when asked by a TMZ reporter if he thinks of Gaye when he writes his music.

Gaye's family is threatening to sue Thicke and his "Blurred Lines" collaborators, the rappers Pharrell and T.I., claiming their No. 1 song is essentially a remake of Gaye's 1977 disco hit, "Got To Give It Up."

"There's a way to do business and a way not to do business and we're not happy with the way he's gone about the business," Gaye's son, Marvin Gaye III, told TMZ.

The "Blurred Lines" collaborators took a preemptive strike against Gaye's heirs by filing a complaint in a California court last month asking a judge to determine that "Blurred Lines" does not copy Gaye's song or take his composition without credit.

"The keys are different. The tempo is different. The structure is different," Thicke's attorney, Howard King, said at the time. "So from a legal standpoint, they're not the same song."

While they await the judge's ruling, the "Blurred Lines" singers have found an ally in another music legend who knew Gaye well, Stevie Wonder.

"It's not the same song," Wonder told a TMZ reporter this week.

Pharrell, for one, says he is still a Gaye fan, even though he thinks Gaye's family is missing the mark.

"I'm a huge fan of Marvin Gaye. He is a genius. He is the patriarch," Pharrell told reporters on the red carpet earlier this month at New York's Fashion Week. "If you read music, all you have to do is read the sheet music. It's completely different."
