Posh Spice plans to cash in on the domino effect in her bid to become a Vegas casino owner.

Victoria Beckham, 34, is teaming up with showbiz pal “Desperate Housewife” Eva Longoria, 33, to launch the unique nightspot which will also include a top-notch restaurant, a British tabloid newspaper is claiming.

Obsession

The idea springs from the pairs’ interest in dominoes — also known as “bones” — after Hollywood couple Ashton Kutcher and Demi Moore introduced them to the game.

A source told Britain’s Daily Star: “Eva and Victoria are obsessed with the game and spend most of their evenings going out for a civilised meal and then getting stuck into a meaty tournament.

“But they realised there are no venues which provide dinner AND focus on this new Hollywood craze.

Energies

“So when Eva said she was opening a new branch of her Beso restaurant in the gambling capital of the world, Victoria had the brainwave of turning it into a place which specialises in food and their favourite game.

“Eva will oversee the restaurant, while Victoria channels her energies into the casino.”

As well as dominoes, the casino will offer Mah Jong, Chicken foot and Cut-Throat.
