A society marriage breakdown has taken a twist with police called in to protect a woman who left her partner for her best friend's husband. Christopher-John Nasser, a Sydney publican and investor, was issued with an Apprehended Domestic Violence Order last month, 'restricting his behaviour' towards his estranged wife Hollie Nasser. Police took out the order in the Local Court to protect Ms Nasser after she left the family home in Sydney's eastern suburbs and moved in with wealth manager Charlie Aitken, the husband of her best friend Ellie. Court documents stated Mr Nasser must adhere to standard conditions including that he must not 'assault, threaten, stalk or intimidate Ms Nasser, or anyone she has a domestic relationship with'. The AVO is due to be heard in court on December 15. Mr Aitken confirmed in a statement last week that he and his lawyer wife of 19-years had separated and he was in a new relationship. 'I can confirm I am separated from Ellie Aitken and am in a relationship with Hollie Nasser. 'My sole focus is my children and I’ll make no further comment,' the statement said. Ellie Aitken, 42, and Charlie Aitken, 48, (pictured together) announced their split in November Hollie Nasser is the wife of Mr Aitken's investment partner Chris Nasser (both pictured) The Nasser's and the Aitken's had been best friends for years, with Mr Nasser an investor and director of the Aitken's wealth management company, until he resigned in early November. Mr Aitken and Ms Nasser are reportedly living together in a serviced apartment in Bondi Junction. Although the two women are no longer friends on Instagram, their comments to each other are still visible. On a post Ms Aitken made to celebrate her wedding anniversary in 2019, her former best friend was quick to comment. 'Happy anniversary!' Ms Nasser wrote. 'Best couple.' In 2019, Hollie Nasser said the Aitkens were the 'best couple' in an Instagram comment Ms Aitken (second left) and Ms Nasser (right) were best friends prior to November 2021 In another post a few weeks later, Ms Aitken uploaded another happy snap of her fund manager husband and said he was the 'kindest, most hardworking person I know'. Last December, Ms Aitken shared a photo with Ms Nasser during an event at the Sydney Opera House where she said she was looking forward to a happy 2021. 'A beautiful day with great friends to mark the end of a tough year,' she wrote. 'To a new one that brings happiness and good times to all.'

'I can confirm I am separated from Ellie Aitken and am in a relationship with Hollie Nasser,' Charlie Aitken said Just a few weeks before the split, Ms Aitken had posted a gushing birthday message to her friend, telling Ms Nasser she was 'so lucky to have you in my life.' The couple were known in elite social circles and counted Australian business giants as friends, including WA mining magnate Andrew 'Twiggy' Forrest and media tycoon James Packer. Until 2016, they lived in a spectacular $11million mansion in Darling Point before moving to a rental property in Bellevue Hill. Ms Aitken was also in high demand on the boards of charities and organisations including the Australian Ballet - making her one of the city's finest networkers and charity fundraisers.

In 2011 however, she transitioned out of the legal sphere and into luxury lifestyle fashion with the launch of her label Aitken And Co. Newcastle-bred Hollie Alford is a former medical research associate who married Mr Nasser at a glittering ceremony in Sydney's St Mary's Cathedral in 2016 before the reception at Quay restaurant. Together the best friends were feted as leading lights of Sydney's social circuit, regularly photographed at functions and charity events.
