Robin Thicke is being sued by the estate of Marvin Gaye for stealing from not one but two of the late music icon's songs, according to court papers.

The family initially claimed that Thicke's hit "Blurred Lines" plagiarized Gaye's 1977 track "Got to Give It Up." Now they say he uses two Gaye songs.

Robin Thicke, Pharrell and T.I. are suing Marvin Gaye's family and Bridgeport Records, insisting that their summer smash "Blurred Lines" is an original hit.

That's right ... the artist accused of ripping off an earlier work is the one suing, not the reverse, leading some to believe it's all part of a big PR effort.
