She's the darling of the fashion world who commands front-row seats, a burgeoning circle of celebrity friends and entry to the hottest parties in town.
But Alexa Chung, 31, insists her life is not the filtered fiesta of fun and games it appears to be for her 1.8million followers on Instagram.
"No one is as happy as they seem on Instagram," Chung says, in an interview with the Telegraph's Stella magazine this weekend.
"Even friends of mine. I’ll say, 'Wow, that looked amazing!' and they’ll be like, 'Nah, it wasn’t.’ I tell them, 'You need to stop putting that stuff up because it looks perfect.’ But then Instagram would be awful if it was reality, wouldn’t it? 'Here are my spaghetti hoops and me crying over EastEnders.'"
The designer has lived in New York for the past six years - but even this, she says, is not the glamorous SATC-style lifestyle that many people assume it to be.
"The thing is, I live in the East Village and my apartment is nothing crazy. The night-time invitations are fancy-pants, but I’m like Cinderella and at the end of the night I have lost a shoe and I am going home in a pumpkin," she says.
In fact, Chung is currently taking a break from the Big Apple as she admits, "I’ve just felt exhausted by it".
"It is really fun. There’s loads of new places opening up. But there is a groove in the ground where I walk back and forth to the same perfect bars. I’m not over New York, but I think rather than going out seven nights a week, I need to stay in sometimes. Make dinner."
Chung is currently curating her latest collection for US denim label AG (Alexa Chung for AG), inspired by American girl gangs - with a bit of quintessential Brit corduroy thrown in ("I just can’t help myself," she says).
The diffusion line is allowing Chung to warm up to launching her very own fashion collection.
"It seems scary," she says. "But everything else has been scary, in hindsight. It’s just that I didn’t have time to think about it. I need to revisit that attitude and get on with it. Everything doesn’t have to be perfect, I’ve realised. You can learn as you go."
The former TV presenter says she became more philosophical about things after turning 30 last year.
"I got more relaxed about things," she says. "It’s as though you are a book and you’re getting through the story and it’s OK. But you’re anticipating this thing happening, which I think came from fear-mongering by magazines: 'What’s going to happen when I’m 30? Do I grow an arm or do something weird?’ Then I saw this Patti Smith thing on YouTube where she says, 'Life is a journey. There are going to be ups and downs and that’s what makes it colourful and interesting.’ So now I’m like, 'Oh, it’s always a bit twisty, so enjoy the moment. Seize the day. Carpe diem.'"
