An explosive new book out from Hunter Biden’s girlfriend Lunden Roberts, the mother of his daughter Navy Joan, tells us even more about his partying days — again raising the question of why so many foreigners would pay this guy millions for any reason except his access to his dad. 

He had his own wing of a Virginia mansion rented by his father where he kept his drug paraphernalia locked up, and brought both his lovers — his dead brother’s wife Hallie and eventual babymama Roberts — there at the same time. 

He met Roberts at a party at his investment firm, where he had stripped down to his skivvies to do drugs in a private office; he lit up a crack pipe and twerked in front of her at the DC strip club where she worked. 

He showered six or seven times per day to “get the demons off him” 

He scored off a dealer named Bicycles, employed a mysterious bodyguard named Big Country and jumped off trains en route from DC to New York to “buy pants.”

He once gave away his jacket, in a fit of kindness, to a homeless man, only to realize he’d left his dead brother’s dog tags in it. (The vagrant was kind enough to return the dog tags.)

Yet this rich-kid addict straight from central casting — this crack-smoking, pole-dancing mobile disaster of a human being — allegedly possessed the experience and smarts to earn millions of dollars in international business. 

Hunter had a $1 million per year board seat at Ukrainian energy company Burisma and inked lucrative deals with Chinese firms.

He, his associates, his family, most of the media and the President of the United States have always insisted those gigs were totally above board and not the result of his selling the Biden name.  

Yeah, we guess keeping the crack torch lit long enough for your next hit is a kind of experience with energy. 

And is arranging meets at 7-11 with your dealer really all that different from taking meetings with brokers of other commodities?

Kidding aside, the American public owes Roberts a debt. 

She’s braver than most journalists and public watchdogs.

And she’s given the lie in the utmost to claims Hunter’s “work” was anything more than payments for influence with the then-vice president by players in countries where Joe Biden was the Obama administration’s point man. 

So put that in your pipe and smoke it, Hunter.
