www.vladtv.com - A few days ago Cali rapper Blu voiced his opinion on the grand jury's decision not to indict the officers involved in the death of 12-year-old Tamir Rice. He then pointed his aim towards Dilated Peoples' Evidence and producer Alchemist with claims his two past collaborators were "PRO DARREN WILSON," the former cop who fatally shot Michael Brown in 2014. Evidence later tweeted out to his followers "My people. Blu is not well mentally...Very talented human being who is having a hard time with life," while calling him one of his "favorite rappers." Industry sources reached out to VladTV exclusively and alleged "Blu is bipolar and a manic depressive," which may explain his erratic behavior. We also spoke to Evidence who disputed the homosexual and cocaine use allegations made by Blu, telling us "neither claims are true." The musician also said he hasn't encountered Blu since February, and this isn't the first time Blu has had a Twitter episode. He apparently had one a while back with Alchemist as well, but he has since deleted the tweets. Check out our latest VladTV news clip for more.
