She’s one of the heirs to her father's billions, so does socialite Petra Ecclestone really shop at the 99 Cent Store?

Sadly the English born socialite isn’t that down-to-earth and was actually walking the aisles of the budget shop in a ball gown pulling a suitcase behind her as part of a photo shoot for charity.

Meet 22-year-old Ekaterina Rybolovleva, the proud owner of New York’s most expensive apartment, courtesy of her über rich daddy, former fertilizer magnate, Dmitry Rybolovlev.

As RadarOnline.com previously reported, the Russian heiress just became the lucky owner of an $88 million luxury apartment, but here are some things that you may not know about the elusive rich girl.

It should come as no surprise that Daphne Guinness’ palatial New York City residence is just as decadent as her taste in fashion!

It’s hard to believe that Daphne Guinness was ever anything less than glamorous!

The eccentric heiress to the Guinness fortune and style icon opens up about her life before she discovered couture and shows off her coveted closet in a new interview with DEPESHA magazine’s Editor in Chief and dot429 Fashion Contributor Stephan Rabimov – and RadarOnline.com has the highlights.

“I was quite a tomboy; I was always falling out of trees. Perhaps this is how my fascination with armor began,” Guinness, who is famous for adorning her body with armor, tells Rabimov.

British heiress, Tamara Ecclestone's mother tells her she has "mental problems" because of her spending, RadarOnline.com can report.

The 27-year-old socialite – the daughter of Formula 1 billionaire Bernie Ecclestone and Croatian model Slavica Ecclestone -  admits she loves her huge wardrobe and accessories collection, though her mom gets annoyed when she sees her excesses.

She said: "I am aware of the recession. My mom is always having a go at me about my spending – when she sees all the clothes in my dressing room she tells me I have mental problems. But I can't pretend this isn't my life.

"OK, I feel bad about it sometimes, but it doesn't make me a horrible person. I'm not going to lie and say I don't love clothes and bags.

It is an heiress high fashion fight!

Billionaire Petra Ecclestone and her new bff Paris Hilton stepped out for dinner Sunday night and each blonde bombshell was decked out in a crazy leopard print pattern.

Newly married Petra was in a white and black leopard print bustier which she paired with skin tight leather pants and spikey Christian Louboutin heels.

Single Paris was in a long length green leopard print dress that she paired with simple black pumps.

The girls are long time friends and have been hanging out frequently since Petra moved to Los Angeles and purchased the Spelling mansion The Manor for $85 million, which she is extensively renovating.

British heiress Daphne Guinness is clearly sticking to her “I’ll eat when I’m dead” mantra!

The ridiculously rich and skinny Guinness heiress demonstrated her kooky style sense at Gareth Pugh’s Spring/Summer 2012 runway show in Paris on Wednesday, watching models parade down the runway in the designer’s Lady Gaga-esque getup – and RadarOnline.com has the photos.

"I'll eat when I'm dead," was the most shocking quip to come out of Daphne Guinness' interview with the New Yorker - but it certainly wasn't the only memorable moment.

The skinny socialite and style icon, who has palled around with everyone from Alexander McQueen and Isabella Blow to Hole frontwoman Courtney Love, opened up to the magazine about her aristocratic background, which has enthralled the world for several decades - dishing on everything from her grandmother's friendship with Adolph Hitler and her philandering father to her career aspirations as a child - and RadarOnline.com has all the highlights of the extensive and intriguing interview.

As aristocratic as they come, the 43-year-old, who the journalist likens to "a slightly deranged fairy invented by C.S. Lewis" is the daughter of Jonathan Guinness, heir to the famous beer fortune, and his second wife.

Jonathan's mother and Daphne's grandmother, Diana Mitford, was a famous Fascist and Nazi supporter, whose second husband, Sir Oswald Moseley, founded the British Union of Fascists.

Diana, who became "very friendly" with Hitler in the 1930's, defended him to the end.

Guinness shares a memorable conversation with her grandmother about her questionable friendship with Hitler: "I said, 'Granny, it just can't be right,' and she just said, 'He didn't photograph well.'  She said he was very, very funny."

While most public figures deny extramarital affairs until the end, Daphne has openly admitted to being involved with a married man. She told Harper's Bazaar in 2011 about French intellectual Bernard-Henri Levy: "He is quite obviously the love of my life. My greatest sorrow has been the unresolved question of the state of our relationship."

Apparently, she learned about these liaisons from her pop - Jonathan Guinness fathered three children with a mistress, while married to Daphne's mother!

And though her marriage to Greek shipping heir Spyros Niarchos bore her three children, she admits it also halted career plans she had for herself - she wanted to sing as an operatic soprano!

"Spyros didn't like classical music, poor him; people either like it or they don't, and you can't criticize someone for that. I would go off and do it somewhere where he couldn't hear me. And he used to think it depressed me, which it didn't."

Who Is Daphne Guinness? Inside Her Stylish & Scandalous Life

Other interesting details from the interview:

She wears white ballet slippers on the StairMaster at the gym. And, she wears diamonds all the time - even to the beach!

After her best friend of several years, Isabella Blow, committed suicide, Guinness purchased the entire collection of Blow's amazing clothes when auctioned off at Christie's, without any intention of wearing them. "It makes me cry," she explained. "It smells of her smell."

Daphne's own clothing collection, which is distributed between her London and NYC homes, consists of over 2,500 garments, 450 pairs of shoes, 70 hats and 200
handbags.

She only wears a custom-blend red nail polish - and carpeted the floors of her NYC apartment in the same hot hue!
