Card king is deck-adent

He’s a card shark by day and a party animal by night!

Famed blackjack mastermind Don Johnson, who has been running roughshod over Atlantic City casinos, let the champagne flow during a wild weekend bender across the pond, according to published reports.

Johnson, 49, really let loose at London’s swanky One4One nightclub, multiple British press reports said yesterday, ringing up a bar tab of 168,118 pounds.

That’s $269,040 in good ol’ Yankee greenbacks!

Johnson made headlines stateside when he claimed to have taken down several Atlantic City casinos for $15 million in blackjack winnings.

Sources close to the casinos and state gaming regulators have said they believe Johnson really did take down the Jersey card houses for massive profits, in a wild winning streak that goes back to late 2010.

The Bensalem, Pa., resident was in London with Garden State rocker pal Jon Bon Jovi.

Johnson certainly partied like a rock star, splashing fellow club-goers with champagne. And not just any bubbly.

The card whiz was hitting the bottle with a massive, 30-liter jug of Armand De Brignac Midas champagne, which went for $192,036. It’s believed to be the world’s most expensive bottle of bubbly.

The final bill included also included:

* A bottle of Armand De Brignac Methuselah that went for a shocking $40,007.

* A bottle of Dom Perignon for a mere $1,200.

* A magnum of Grey Goose for $672.

* And four Red Bulls for $32.

The bottom line included an automatic 15-percent service charge of $35,902.

No one picked up the phone at Johnson’s Pennsylvania home yesterday.

The no-holds-barred partying at the famed Park Lane hot spot runs in complete contrast to Johnson’s previously quiet, unassuming public persona.

The 21 player usually dresses casually when he’s at the tables, often wearing freebie caps given away by all the casinos he’s visited.

If it’s cool outside or the air conditioning is blasting in the casino, Johnson will often don an Oregon State Beavers hooded sweatshirt, in honor of his Pacific Northwest roots.

Now that he’s got a taste of the hard-partying lifestyle, Johnson reportedly plans to host a major Las Vegas bash this summer — for the birthday of timeless sex symbol Pamela Anderson.
