19 Shocking Things You Never Knew About Princess Margaret

The heir and the spare: Born in August, 1930, The Queen's younger sister Princess Margaret, Countess of Snowdon, was well-known for her irreverent approach to life. Here, the young princesses pose in matching outfits at Buckingham Palace in 1942.

Princess Margaret lived a wonderful life as a little girl, but it changed forever when her father reluctantly and unexpectedly became King after his brother abdicated from the throne. Here, King George and the Queen Mother spend time with their daughters at the Royal Lodge in Windsor in 1946.

The stunning royal, pictured in 1966 attending the Balmain fashion show at Paris Fashion Week, was praised for her elegant style. It even rivals that of Princess Diana.

But it was the trials and tribulations of her personal life that truly captured the world's imagination. She sure went through it all.

In 1952, Margaret fell head over heels in love with Group Captain Peter Woolridge Townsend, and he proposed. However, after consulting the Queen, she rejected his offer of marriage as he was a divorcé and, therefore, an unsuitable match in the eyes of the Church of England.

"I would like it to be known that I have decided not to marry Group Captain Peter Townsend. But mindful of the Church's teachings that Christian marriage is indissoluble, and conscious of my duty to the Commonwealth, I have resolved to put these considerations before others," she explained at the time.

She went on to marry photographer Anthony Armstrong-Jones in a lavish ceremony at London's Westminster Abbey in 1960. Sadly, they divorced in 1978 after wide-spread rumors of Margaret's infidelity surfaced.

Before their relationship soured, they were quite an attractive couple. A year after tying the knot, the couple welcomed their first son, David, Viscount Linley. What a sweet baby!

“She was rather sidelined, and that’s why she became this outgoing, extravagant person because she felt she had to make her mark in some way,” close friend Lady Jane Rayne revealed in the documentary Princess Margaret--A Love Story.

With her older sister taking the crown and royal responsibility, Princess Margaret was much like cheeky Prince Harry--rubbing shoulders with glamorous celebrities and hitting the social scene. In 1965, the Princess charmed the Beatles, while these days Harry is constantly hanging out with A-listers.

It's long been rumored the Queen's younger sister had an affair with Rolling Stones frontman, Mick Jagger. According to a courtier in The Wild Life And Mad Genius Of Mick Jagger by Christopher Andersen, she found the singer "sexy and exciting."

Decked out in her finest jewels Princess Margaret puffs back on a cigarette at the Gala For Aids Crisis Trust in 1991. Like her father, the royal was a heavy smoker, and in 1985, she had part of her left lung removed.

Her proudest achievements! Margaret's children David Armstrong-Jones, Viscount Linley, and Lady Sarah Chatto attend the Queen Mother's 87th birthday celebrations in 1987.

Prince Edward, the Queen, Princess Diana, The Queen Mother, Prince Charles and Princess Margaret wave to well-wishers outside Clarence House in London on the Queen Mother's 90th birthday in 1990.

"When my sister and I were growing up, she was made out to be the goody-goody one," she claimed to Andrew Duncan, who wrote The Reality of Monarchy.

Princess Margaret sadly passed away in 2002 from a stroke. Seven weeks after her tragic passing, The Queen Mother died in her sleep at 101 years old.

Her memory is still alive and well in her grandson Arthur Chatto, whose mother is Lady Sarah Chatto. And he's grown up to be quite the handsome young man.

Unlike his first cousins, Arthur enjoys a more low-key life away from royal duties. However, in 2006, he acted as a page when William was installed as a knight of the Thistle. And in 2008, he joined his famous family for their traditional church service in Sandringham.

Arthur is now an ambitious teenager who attends the prestigious Eton College in Berkshire where cousins Prince William and Prince Harry also studied. If the Queen ever decided to abdicate from the throne and thus Margaret had to step up, Arthur and his big brother Samuel would be the equivalent of Princes William and Harry.
