Kate Moss' brother Nick led the birthday tributes on Friday as the supermodel celebrated her 52nd birthday at swanky London hotspot, Cecconi's Mayfair. 

Nick, 47, took to his Instagram Stories to share a sweet selfie with his famous sister outside the lavish Italian restaurant, wishing her a happy birthday. 

The fashion icon looked effortlessly chic in a red-and-white striped shirt, which she paired with oversized orange-tinted shades, while Nick wrapped up warm in a black scarf as he leaned his head against Kate's for the snap. 

Tagging the restaurant in the post, he captioned the photo: 'Happy birthday big sis ❤️'

Nick, who now runs a Vietnamese street food truck called Vietvan, has largely stayed out of the spotlight over the years.

He previously told how he 'never wanted to piggyback on [Kate's] fame', despite admitting she 'can open doors'.

Speaking to The Sunday Times Style magazine, he said: 'You see people on the coat-tails of other people's success and it's cringy and embarrassing. You want to be your own person.' 

Kate was one of the most recognisable faces of the 90s, storming the runway at prestigious shows and covering all the glossy magazines. 

Yet over the years, her career hasn't always been smooth sailing, with the star having weathered the 'Cocaine Kate' storm of 2005 after infamously being pictured next to lines of white powder.

After years of hard partying, cigarettes and alcohol – now, aged 52, Kate is looking younger than ever, having adopted a well-thought-out health and wellness regime over the course of her thirty years in the industry.

While she's often pictured attending a celeb pal's birthday celebrations here and there, her party lifestyle is a far cry from what it used to be. 

After years of watching some of the best professionals in the beauty business, Kate has learnt all the tips and tricks when it comes to looking ageless.

She once said that 'sitting in a make-up chair' during her early modelling days had made her learn from the most amazing experts.

Nowadays, Kate has regular juice fasts, and favours the week-long juice-only programme at wellness LifeCo resort in Turkey – she's visited every year for the past decade. 

She is also the proud owner of wellness business Cosmoss, which sells a range of own-brand teas, skincare products and a book of 150 'positive messages'.

Kate has a £4,000 Cadillac Pilates reformer machine at home, and personal trainer, Hortense Suleyman.

A magazine source said: 'The brand is late on the bandwagon — candles, serums and perfume are all quite middle-aged. But she's been having lots of meetings with people and Cosmoss is stocked in Harrods. I know she has great hopes for it.'

Over the years, Kate has given an insight into how she stays looking so good, revealing her tips and tricks for maintaining her youthful look. 

She told Net A Porter: 'I stay hydrated on the flight and try to eat only light foods. I find adapting to the new time zone as soon as I arrive is helpful, so I try to stay up until my usual bedtime.

'I've recently undergone red-light LED therapy and use the Talika Time Control + device. It's great, as it's small and easy to travel with, and I can definitely see an improvement in my skin. I have rose quartz and jade gua sha tools that I use, too.'

Other beauty tips favoured by Kate include dunking her face in iced water and depuffing her eyes with cucumber slices. 

Speaking previously about how she tackles a 'bad face day', she said: 'My old go-to trick is to plunge my face into a bowl of iced water and cucumber slices – it instantly tightens and gets rid of any puffiness.

'I then use Cosmoss Golden Nectar facial-oil drops with my gua sha. Together, they give your skin that extra glow and are great at detoxifying and lymphatic drainage.'

Another tip Kate claims she follows is staying out of the sun, after previously being warned by her friend and make-up artist Charlotte Tilbury.

She told Grazia: 'Charlotte Tilbury told me not to go out in the sun, but it's because she's a redhead, so she knows. I kind of ignored her, but now I'm taking no risks!'

Kate also revealed she keeps her body refreshed by doing three week-long juice cleanses throughout the year. 

She said: 'I juice. At least three times a year, for a week, I do a juice cleanse. I like it. I feel amazing. And then I have so much energy! Everyone else is like, "Please…shhhh…" Oh my god, I have so much energy, start bouncing off walls!'
