In the frame, Isla is all smiles as she drinks in the sunshine and appears to enjoy a beverage.
Isla captioned the image, shared to her 1.9milion followers, with some heartfelt words.
The couple announced the news by sharing a picture of themselves together wearing tennis gear.
Their statement read: ‘After a long tennis match lasting over 20 years, we are finally putting our racquets down.
‘In 2023 we jointly filed to end our marriage. We have always prioritized our privacy and have been quietly working through this change.
‘We forever share in our devotion and love for our children. We sincerely appreciate your respecting our family’s wish for privacy.’
The couple first met back in 2001 and tied the knot in 2010.
They are parents to daughters Olive, 17 and Elula, 13, and son Montgomery, nine.
Insiders have claimed their marriage had been ‘shaky’ for years, with Sacha reportedly struggling after making the ‘sacrifice’ to relocate their family to Australia back in 2020.
They had moved from Los Angeles to Sydney in 2020, then to Perth – where Isla’s family live – in September 2021, to escape Sydney’s strict Covid lockdown rules.
At the time, they said the switch to Western Australia would be permanent.
However, their move from the US to Australia was said to be ‘difficult’ for Baron Cohen because he was settled in Hollywood, and it was a shorter flight to London from there, too.
