Wiz Khalifa is telling friends there's a ZERO percent chance he ripped his smash hit "Black and Yellow" from a lesser known song called "Pink N Yellow" ... 'cause he's never EVER listened to the track ... this according to sources close to Wiz.
We're told Wiz is adamant he would never jack lyrics from another artist ... despite the allegations in a new $2.3 million lawsuit filed by a Pennsylvania rapper named Maxamillion.
Max claims he copyrighted "Pink N Yellow" in 2008 ... three years before Wiz released "Black and Yellow."
But one source close to Wiz tells TMZ ... "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."
TMZ also spoke with Max's attorney ... who tells us Wiz SHOULD know who Max is ... because the two sides had spoken about a potential settlement recently. We're told Wiz's people were not open to a deal.
A rep for Wiz had no comment.
