Elisabetta Gregoraci shows off her bikini body

Six weeks after their romantic Roman wedding, it appears the honeymoon still isn't over for Formula One boss Flavio Briatore and his new wife Elisabetta Gregoraci.

While most newlyweds spent an average of two weeks on holiday following their nuptials, billionaire Flavio can afford to extend his romantic vacation.

But the vacation isn't as intimate as the couple may have hoped for, they have been joined by a host of friends, including retail tycoon Sir Philip Green.

The couple have been holidaying on a yacht docked in Sardinia over the last few weeks, giving 28-year-old model Elisabetta plenty of opportunity to show off her stunning figure in a series of eye-catching bikinis.

Despite his new wife's striking curves, portly Flavio was content enough with his larger size to let it all hang out.

The couple, who share a 30 year age gap, attracted a lot of attention as they strolled down the beach in Marinella surrounded by their huge entourage.

Dressed in a plunging violet cut-out swimsuit, over-sized gold earrings and designer sunglasses, Elisabetta was the epitome of Mediterranean beach chic as she cooled off from the sizzling temperatures.

And not forgetting Elisabetta's 18k white gold wedding ring, designed by exclusive jeweller DeGrisogono.

The couple wed in a 12th century basilica in the Italian capital on June 14th after a two year courtship.

Elisabetta is just the latest in a list of famous beauties to date the racing tycoon.

Flavio previously dated Naomi Campbell, Adriana Volpe and Heidi Klum, with whom he fathered a daughter Leni, now four.
