Char is fake as hell so I'm not surprised. He rides with anyone who endorses his ass kissing. Once Iggy came to the Breakfast Club earlier this year, he's been riding her bandwagon. Of course Nicki is going to take offense to that when he claimed he was here for her 2010 - 2013 and nobody else is touching her.
Even when LAN came out, he wasn't impressed by it at all. He was already on the anti-Nicki ship and acting underwhelmed by anything she released this year.
This isn't Nicki taking offense to radio DJs who don't support her every waking moment, it's Char being an insincere friend (because they were that close) and supporter in the industry. Nicki considered Char a lot higher than other industry interviewers and DJs and he proved to be as fake as the rest.
I'll wait for when he starts bashing Iggy and Kim again and kisses Nicki's ass next month.
