marvin gaye 3rd*It should come as no surprise that Marvin Gaye III is not thrilled with Robin Thicke‘s plan to file a lawsuit against the Gaye estate over “Blurred Lines.”

Marvin Gaye’s son was on “TMZ Live” on Wednesday and pretty much sai8d he plans to respond with his own suit against Thicke.

Basically he’s not happy with Thicke, saying the blue-eyed soulster disrespected the Gaye family by shamelessly lifting his father’s song (“Got to Give it Up”) for the hit tune (plus many other Thicke tracks).

As we reported, Thicke has filed a lawsuit against the Gaye estate, asking a judge to head off any legal action from the Gayes by ruling “Blurred Lines” does NOT violate Marvin’s copyrights.

When TMZ asked Marvin III directly if he was going to sue Thicke for copyright infringement, but it was pretty clear that’s where things could be headed.
