Robin Thicke, along with producer Pharrell Williams and rapper T.I., have filed suit against deceased singer’s Marvin Gaye’s family in an effort to protect their summer hit song, "Blurred Lines," which many have said bares too close of a resemblance to Gaye’s 1977 hit "Got to Give It Up."

In filing the suit, the trio said that while they have "the utmost respect for and admiration of Marvin Gaye, Funkadelic and their musical legacies," they must "reluctantly file this action in the face of multiple adverse claims from alleged successors in interest to those artists."
