The Nassers and Aitkens were two of Sydney's high-flying power couples before a scandalous love triangle tore them apart.
Millionaire publican Christopher Nasser was close friends with investment banker Charlie Aitken and director of his firm Aitken Investment Management.
His socialite wife Hollie was also best friends with Mr Aitken's partner and hotshot lawyer-turned-fashion-guru Ellie.
For years, the quartet were inseparable - taking luxurious international trips together and raising their young families as business partners and best friends.
The two couples mingled in high society and social circles that included the likes of Julie Bishop, Russell Crowe and James Packer.

Hollie regularly described her best friend's marriage as perfect, telling them they were the 'best couple' and lavishing praise on their young family.
On Sunday, it became evident the friendships were damaged irreparably when Ellie shared a text exchange on Instagram accusing Hollie of 'bullying' her.
Last month, Mr Aitken revealed he and his wife of 19 years had separated, and he had struck up a relationship with Hollie.
Their former partners are 'reeling' from the revelation, with former friends saying they've all 'distanced themselves' and are 'horrified with the nature of what's gone on'.
But it isn't just their personal lives impacted by the new coupling. Given their close business partnerships and standing within the community, the ramifications of the friendship split are reverberating throughout the eastern suburbs.

Christopher Nasser was 'totally blindsided' when he learned of the new relationship between his wife of five years and business partner.
It's understood he discovered the relationship via a baby monitor which was left on in his eastern suburbs marital home.
Mr Nasser is a millionaire publican who owned The Crescent, in Fairfield, Sydney's west.
He was also an investor and director of the investment firm Aitken Investment Management - which was set up by Mr Aitken.
Mr Nasser reportedly funnelled between $5million and $10million into the firm since 2015.
He resigned from his role as director after the new relationship was made public in early November.
In his place, he appointed his brother Damien Nasser to take control of the family's portfolio.

On Thursday, he sold down about $7.5 million from AIM's global high conviction fund comprising a basket of high-performing international low to mid-cap stocks.
Friends have rallied behind Mr Nasser, describing him as an 'upstanding guy' who is struggling with the attention that has come with his relationship bust up.
Ms Nasser took out an apprehended violence order against him, which he plans to fight in court.
'After being deeply hurt by the deception, choices and actions of other adult parties, I am disturbed that those actions have been followed by manufactured and dishonest claims now being made about me,' he said.
'I categorically deny the allegations. They are totally baseless. It is disappointing that others are choosing to make a horrible situation for me and my children, even worse.'
The two couples mingled in high society and rotated in social circles that included the likes of Julie Bishop, Russell Crowe and James Packer (pictured, Ellie Aitken, in red, alongside former Liberal Party deputy leader Julie Bishop, centre, with Hollie Nasser, in blue, at Ms Aitken's 40th birthday party in 2019)

Mr Aitken is the investor and former stockbroker who created Aitken Investment Management.
AIM has drawn in big names such as Channel 7's billionaire owner Kerry Stokes.
In June, Mr Stokes is said to have pulled all his investments from Mr Aitken's funds.
The 48-year-old businessman has held top roles at several firms including director and head of Sydney Sales Trading at Citigroup, executive director and partner of Southern Cross Equities and executive director and board member of the ASX listed Bell Financial Group.
He took a leap of faith in 2015 launching his firm alongside his wife, selling up their spectacular $11million mansion in Darling Point to help free up cash.
