Season one of The Crown heavily focused on the tragic romance between Princess Margaret and Group Captain Peter Townsend (Ben Miles).
But despite the strong backing of the public, the star-crossed lovers could never be together because Townsend was a divorcee.
The Netflix series left the Princess heart-broken and resentful towards her sister Queen Elizabeth (Claire Foy).
But season two now promises to build on a budding new romance with photographer Antony Armstrong-Jones.
Peter Morgan, writer of The Crown, said: “Tony is everything the palace isn’t: seductive, dangerous, risqué – remarkably modern and progressive.
“He’s a source of great happiness for Margaret, tired of the buttoned-down conservatism of palace life, but he hides dark secrets. He brings a new flavour and rhythm to proceedings.”
Did Princess Margaret marry Lord Snowdon?
About four years after she split up with Captain Townsend, Margaret got engaged to photographer Antony Armstrong-Jones.
Their relationship was kept on the quiet side for a while before they took the public by surprise with their engagement.
Margaret reportedly accepted his proposal a day after she found out Townsend was going to marry a young Belgian woman.
The couple got married at Westminster Abbey on May 6, 1960, with Prince Philip escorting the Princess to the altar.
The grand ceremony caught the ire of European royalty because the groom was a commoner, but the wedding was broadcasted to the world via television regardless.
Upon their marriage, Antony was named the Earl of Snowdon until 1999 when he earned a life peerage and became Lord Snowdon.
But the marriage did not last very long and was plagued with rumours of unfaithfulness on both sides.
In fact, a close friend of Snowdon’s once quipped: “If it moves, he’ll have it.”
The couple split in 1976 after photographs were published of the princess in the company of another man, Roddy Llewellyn. Their divorce took place in May 1978.
Margaret and Antony had two children together – David, born November 3, 1961, and Sarah, born May 1, 1964.
Who plays Lord Snowdon on The Crown?
Downtown Abbey fans were glad to recognise the familiar face of Matthew Goode in the role of Lord Snowdon.
Matthew made his TV debut in 20002 on ABC’s TV film Confessions of an Ugly Stepsister.
He has since starred in a string of TV shows including Agatha Christie’s Marple and Dancing on the Edge.
Comic book buffs will also recognise him as as Ozymandias in Zack Snyder’s 2009 adaptation of the grim Alan Moore graphic novel Watchmen.
The Crown season 2 will drop on Netflix on December 8.
