"The Forbes list just changed."That is the boast made by singer-songwriter Tyrese Gibson in a
video posted on Facebook (and later removed), before he is pushed aside by Dr Dre, the co-founder of the Beats Electronics firm.
The list of the richest people on the planet, says Dre, the 49-year-old hip-hop star and entrepreneur, has changed "in a big way".
"The first billionaire in hip hop right here from the... West Coast, believe me," he sayd, before the video abruptly ends.
By most accounts, Apple's $3bn (£1.8bn) acquisition of the Beats headphone and music streaming service will increase Dre's net worth from an estimated $550m to almost $800m - making him, if not hip-hop's first billionaire, certainly hip-hop's wealthiest man.
So how did Dr Dre, born Andre Romelle Young in inner-city Los Angeles, build his fortune?
Borne of necessity
Dan Charnas, a former hip-hop record producer and author of The Big Payback: The History of the Business of Hip-Hop, says that Dr Dre's business acumen was shaped by the culture of hip-hop in the 1980s, which was by necessity more entrepreneurial.
"Russell Simmons [and Rick Rubin] had to start their own music company if people were going to hear these records," he adds, referring to Def Jam records, one of the first and most successful hip-hop labels.
"The hustle of that extended to everything."
Dr Dre was certainly part of that early, scrappy hip-hop milieu.
Although he first found success as a musician with the World Class Wreckin' Cru and then with the seminal group N.W.A. - pioneers of gangsta rap - he was also a keen collaborator and producer, thus ensuring he had two revenue streams: one from performing, and another from producing.
Just a year after he released his debut album, The Chronic, in 1992 - which sold three million copies and won a Grammy award - Dr Dre also helped produce Snoop Dogg's first album, Doggystyle, which sold an astonishing five million copies.
After a falling out with his first label, Death Row Records, due to a contract dispute (among other concerns), Dre negotiated a deal with Interscope to start his own label, Aftermath Entertainment, in 1996.
He then signed and helped produce albums by young hip-hop artists, most notably Eminem, before selling his share of the label back to Interscope in 2001 for a reported $35m.
