Kendrick Lamar Boycotted GQ Party Over 'Offensive' Interview

Despite being named GQ's Rapper of the Year, Kendrick Lamar completely BLEW OFF the mag's Men of the Year Party on Tuesday ... all because he hated the way he was portrayed in his big interview.

In the interview, which GQ released this week, writer Steve Marsh expresses surprise at Kendrick's discipline -- refusing to drink excessively and womanize like other rappers, especially because the over-the-top lifestyle is so prevalent in the game these days.

The writer also spends a lot of time talking about the gang violence endemic in Kendrick's hometown of Compton, which marred rap's history.

And Kendrick and his camp are PISSED, insisting Marsh focused on the wrong details, senselessly romanticizing a dark time in hip hop, when the article should have been a celebration of Kendrick's successes.

The CEO of Kendrick's label Top Dawg Entertainment Anthony Tiffith tells us the interview portrayed him and his company in a negative light and he won't stand for it -- "To say he was 'surprised at our discipline' is completely disrespectful ... Kendrick deserved to be accurately documented."

Tiffith says, "The racial overtones immediately reminded everyone of a time in hip-hop that was destroyed by violence, resulting in the loss of two of our biggest stars [Tupac and B.I.G.] ... As a result of this misrepresentation, I pulled Kendrick from his performance at GQ's annual Man Of The Year party."
