Want to know what money tastes like? Billionaire Petra Ecclestone can tell you.

The 22-year-old heiress posed provocatively with a wad of $100 bills in her mouth and Breaking Celebrity News has the photos of her rich and racy photo shoot.

Petra, who paid a whopping $85 million for Candy Spelling’s Holmby Hills mansion, said that while she might be the richest girl in town she is down to earth -- sort of! 

“With time, people will get to know the real me and realize that I’m not going to parties and falling out of my dress and getting drunk and all that,” Petra told Flaunt magazine, in a thinly veiled dig at her fellow fellow socialites.

The daughter of Formula 1 boss Bernie Ecclestone admits that she has a glamorous lifestyle but insists that she is wise beyond her years.

“Obviously, I don’t sit at home knitting all night long, but I am very mature at the end of the day.”
