Tekashi 6ix9ine is not dropping his beef with Meek Mill. In the latest development of their long-running feud, the rainbow-haired rapper challenged Meek to a one-on-one fight in a video posted to Instagram on March 8. Tekashi also tried to insist that he has more money than Meek by flaunting his fleet of luxurious vehicles (including many Lamborghinis) and sparkly watches.
