The video was posted to Facebook overnight, and shows Dre celebrating in his studio. At one point, Dr. Dre describes himself as "the first billionaire in hip hop." Gibson reiterates the $3.2 billion figure mentioned yesterday, adding that Forbes ought to revise its list of the world's richest people, because Dre is now in the "billionaire boys club."
It's worth noting that Dre doesn't explicitly confirm the acquisition, but the implication here is that it's a done deal. You can watch the full video on Facebook—though be warned that there are some naughty words in use. As you'd expect. [Facebook via Verge]
