Isla Fisher celebrates her 50th birthday in London with close friends including Michelle Dockery and Helen Fielding

Isla Fisher looked in good spirits as she celebrated her 50th birthday in London with a group of close friends, including Downton Abbey's Michelle Dockery.

The actress, who divorced Sacha Baron Cohen in 2024 after 14 years of marriage, beamed as she shared a hug with Michelle.

Isla donned a black blazer and a dark, low cut top for the festivities and let her red locks fall loose down her shoulders.   

Bridget Jones author Helen Fielding was among those who presented the Hollywood star with a two-tiered red velvet cake.

It featured white icing that read 'Happy Beloved Isla Day', adorned with candles, sparklers, palm trees and miniature plastic animals, including her English sheepdog Maisy, horses, and a kangaroo to symbolise her native Australia.

Sacha praised his ex-wife as 'the funniest person, a brilliant talent and a fantastic mum' in a gushing post celebrating her birthday.

The Borat actor proved their is no bad blood between the pair as he mark his ex-wife's milestone birthday with a sweet photo of Isla wearing a bold orange cap while sitting at a beachside cafe. 

Sacha gushed: 'Happy birthday to the funniest, most joyful person, a brilliant talent, and a fantastic mum. May the next decade be even better.' 

The former couple are proud parents to three children. 

It comes after Isla revealed how she has spent the last two years since her split from Sacha focusing on work and herself.

Sacha's approach to single life though has so far been in stark contrast to Isla's.

Only three months after the exes confirmed their divorce was complete, it was reported the Borat star had moved on with a younger model - Hannah Palmer, 27. 

Then in November, the actor was snapped with social media star Kelsey Calemine, 26, who is 28 years his junior.

Speaking to NewBeauty Isla said: 'It has been a really challenging time. I definitely feel like there's something about the divorce club that anyone in it understands in a way other people don't. It's a different grief.'

Switching to a more uplifting outlook, Isla added: 'I feel like creating a new identity after your divorce is so fun, though. You get to reflect on your values and goals, explore new interests, focus on what you want and rebuild your sense of self.'

She explained that she's enjoying having the headspace and time to focus on herself.

'It's a lot like that, reconnecting to maybe passions you had when you were a kid, but they fell by the wayside when you were raising a family,' she said.

'All the relationships that you have in your life that were not necessarily the forefront of the way that you spend your time, because you're married. 

'Those relationships that are so supportive and brilliant and often really, really old get to retake centre stage. I think that's a really exciting thing.'

Isla added: 'There are lots of positives that have come about from all this - like self-exploration and just trying to be kind to myself. 

'I can just give myself grace whenever I like. That's all I'm trying to do.'

Last year, Isla admitted she is not looking to date again anytime soon in the wake of her divorce.

'That's not on my to-do list. I'm not ready to think about any of that,' she told The Sunday Times, explaining her own parents separated when she was nine-years-old and admitting their peaceful arrangement was what she now strives for.
