The former actress was in attendance as Matthews celebrated the milestone with a lavish party for close friends and family members at upmarket Knightsbridge brasserie Sale e Pepe Mare.
Opting for an elegant black evening dress with a dramatic plunging detail, Taylor, 48, commanded attention during a rare night out in the English capital, where she was joined by comedian and former singer .
With old friend also on the guest list, Wednesday's event gave three former members of the notorious Primrose Hill set an opportunity to turn back the clocks - albeit without the associated excess.
Now 18 years sober, Taylor has committed herself to health and wellness after curbing her notorious party lifestyle in the late 2000s.
Along with supermodel , Taylor, Matthews and Frost were core members of the Primrose Hill set, a large group of hard-partying celebrities nested within the north-west London enclave throughout the 1990s.
Davinia Taylor ensured she was in attendance as close friend and fellow Primrose Hill set veteran Meg Matthews celebrated her 60th birthday on Wednesday evening
Lancashire-based Taylor, who previously that if she had 'one more drink, she could have died', now has a biological age of 20 - thanks to a regime of exercise, bone broth and infrared light.
'Last year I did a GlycanAge test, which analyses glycans (sugar structures on proteins), measures inflammation in the body and estimates your biological age. Mine came back at 20!,' she told the Daily Mail in 2025.
'Numbers aren't the point. What matters is how I feel. I'm stronger than I've ever been. My head's clearer. I've got more energy and resilience than I did in my teens, 20s or 30s. I don't feel like I'm fighting my body any more but working with it.
'Longevity has always felt personal to me. My great-grandmother lived into her 80s. My grandmother died in her 70s. My mum died of cancer at 60.
'This isn't about vanity or chasing youth. It's about staying sharp, capable and fully alive for as long as I can – and doing it on my own terms.'
At one point, though, she was famed for her position in the Primrose Hill set, partying through the '90s with friends including Kate Moss, , and , as well as ex-husband Dave Gardner.
But the former actress claims her wild lifestyle almost killed her before she finally stopped drinking and embraced a healthier lifestyle.
'I was constantly hungover, riddled with anxiety, and alcohol didn't work for me any more,' she told The Sun.
'Not even a glass of red wine would lift me. I was shown these awful videos of myself drunk, and numerous times I was told by doctors, 'one more drink will kill you'.
Taylor ditched her party girl ways in favour of a cleaner existence, after a 12-week rehab stint in South Africa where she was eventually able to kick her habits.
The former actress described her battle with alcoholism as a an 'eternal hell', because she knew she shouldn't be drinking but was in a heavy period of withdrawal.
Once she got sober Taylor said she became addicted to other areas of life, such as eating when she gained 'stones', before eventually finding a happier balance.

Sadie Frost, another prominent member of the Primrose Hill set, was also in attendance as Meg Matthews celebrated her 60th birthday on Wednesday evening
She shares son Grey, 18, with Gardner, Luxx, 14, whose father has never been revealed, and Asa, seven, and Jude, eight, with her partner Matthew Leyden.
Taylor told how she wished her mother, who died in 2013, could see the woman she has become since entering recovery.
She told The Sun: 'For her to see me now, as a mother – happy, settled and not needing the fineries to support my ego – would have made her really proud.'
At one point in her life, Taylor faced a custody battle and was suicidal, however, now she said her old self would not have been able to recognise the woman she is today.
Explaining why her younger years were so wild, the former actress said that she has a high dopamine drive, meaning the impulsiveness to do things to feel alive was stronger.
She said that this is a classic symptom of ADHD, but that it is not as widely diagnosed in women as it is in men.
'A girl with ADHD will be referred to as 'Dolly Daydream', and that was me,' she said.
'I'm hoping over the next few years that a lot of women my age realise they can get help for it now – it's not too late.'
