Wiz Khalifa's $2.3 million copyright infringement suit

A Pennsylvania man wants a large chunk of the cash Wiz Khalifa uses to support his very expensive weed habit.

The Pittsburgh native son -- a self-professed marijuana addict -- has been slapped with a $2.3 million lawsuit from a songwriter who claims Wiz ripped off his 2010 chart-topper "Black and Yellow" from him.

Meet Max Warren.

Warren is a Philadelphia-based emcee who performs under the stage name Maxamillion. He says Khalifa's signature song was lifted from "Pink N Yellow," a work Warren copyrighted in 2008.

That's a full three years before "Black and Yellow" landed a copyright in 2011.

A coincidence? Max doesn't think so.

Khalifa (born Cameron Jibril Thomaz), two other songwriters and several record companies and music publishers are named as plaintiffs in a copyright infringement lawsuit filed in federal court in Philadelphia this week. Warren is seeking at least $2.3 million in damages.

"Black and Yellow" was adopted as the unofficial theme song of the Pittsburgh Steelers' 2011 trip to the Super Bowl.

While mum publicly, Wiz is reportedly saying plenty about the song theft allegation and Warren's lawsuit in private.

"Wiz has never heard of this guy… it's just a plot that happens all the the time to rappers to get money. This is just some no-name rapper who wants to get paid," a pal of the lyricist spat to TMZ Thursday.

Attorneys for Warren tell a different story. According to the legal team, Wiz's people had been in contact with them in hopes of reaching a settlement deal in the days leading up to Thursday's court filing.
