Black Eyed Peas star will.i.am has filed a lawsuit against singer/producer Pharrell.

will.i.am previously filed a cease and desist letter that demanded Pharrell dropped the 'I AM' from his "i am OTHER" creative brand.

will.i.am is now countersuing Pharrell, making claims that he has a long history of being a copycat according to TMZ. will.i.am. mentioned that Pharrell is currently being sued by the family of Marvin Gaye, claiming that he ripped of "Got to Give it Up" in this summer's Robin Thicke hit "Blurred Lines."

will.i.am claims that using 'I AM' will confuse people since he and Pharrell are on the same record label and have similar music styles.

"I am disappointed that Will, a fellow artist, would file a case against me," Pharrell tells Rolling Stone. "I am someone who likes to talk things out and, in fact, I attempted to do just that on many occasions. I am surprised in how this is being handled and I am confident that Will's trademark claims will ultimately be found to be as meritless and ridiculous as I do."
