Blac Chyna's new man is all-in on her brand ... and they're both making sure Rob Kardashian's aware.
Chyna - Singer - Mechie - Weeks - Video
Chyna and singer Mechie -- who she's been hooking up with for a couple weeks -- shot a video showing off a very fresh looking 'BC' tattoo behind his ear. If it wasn't clear already ... she's definitely moved on from Rob.
She has a bad history with tattoos and dudes (*cough, Future*) ... so, interesting that HE got the ink...
