After a fairytale $6.5 million wedding in Italy, that outshone even Kim Kardashian's nuptials, stunning socialite Petra Ecclestone landed in Los Angeles on Thursday.

The 22-year-old daughter of billionaire Formula 1 boss Bernie Ecclestone touched down with her husband of five days, James Stunt, to kick-start their married life together.

Robin Thicke and Earth, Wind and Fire are nothing to sneeze at but when billionaire heiress Petra Ecclestone married on Saturday, she had opera superstar Andrea Bocelli serenading the guests before the sunset ceremony, rock icon Eric Clapton playing the newlywed's first dance and none other than The Black Eyed Peas as the dance band!

Now that's a wedding!

Petra's walk-down-the-aisle with James Stunt is estimated to have cost $6.5 million, and there wasn't a cable network paying the tab. Of course that's small potatoes for the 22-year-old who recently paid $85 million for Candy Spelling's Los Angeles estate.

There were no signs of wedding day nerves for the daughter of Formula 1 boss Bernie Ecclestone as she arrived at her over-the-top nuptials in the back of a Rolls Royce looking calm and collected.

No expense was spared for the magical event at a castle in the Italian town of Bracciano -- the same one where Tom Cruise and Katie Holmes wed in 2006 --  with guests sipping on $6,000 a bottle wine and Louis Roederer Cristal Champagne while watching acrobats and fireworks.

The bride's custom-made Vera Wang dress reportedly cost in the region of $120,000.

Her sister, Tamara, was Petra's maid of honor.
