Isla Fisher gushes about husband Sacha Baron Cohen as she stuns in a photoshoot for  Marie Claire

Isla Fisher has spoken candidly about her marriage to Sacha Baron Cohen and their decision to relocate Down Under with their three children.

The notoriously private actress, 45, told the latest issue of Marie Claire Australia she felt ‘very lucky to have met’ the Borat star, 49, at a party in Sydney in 2002.

Isla’s in-depth interview was accompanied by a stunning photo shoot in which she posed in a variety of designer outfits.

Isla was asked to reveal the ‘secret’ to her long-lasting relationship with the British comedian as they approach 20 years together, and she said that ‘humour helps’.

‘I wish I had an answer. I’m very lucky to have met him,’ she added.

She also touched upon how grateful she is for everything in her life.

‘I’m always surprised that I’m employed, married and have my family – everything else feels like a bonus,’ the mother of three said.

Isla added that while motherhood is her ‘favourite topic’, she doesn’t like to discuss her children in interviews to protect their privacy and ensure they have a ‘normal childhood’. 

Isla, who was born in Oman but grew up in Perth, also discussed moving back to Australia with her family after years spent living in Los Angeles.

While reports suggested she and Sacha had wanted to escape ‘Trump’s America’, Isla said relocating to Sydney was a personal rather than a political decision. 

Isla said it ‘feels very magical’ to be back home after spending so long in the U.S. and that she can ‘be herself’ in Australia.
