1. Alexa Chung, TV presenter
Alexa Chung walks out to Shoreditch House's rooftop pool with wide worried eyes. 'Umm, are you going to get me to pose all splayed on the sun lounger?' she asks the photographer. 'Because I'm perhaps the least sexy person in the world.' Some would disagree. The waiter would disagree. His cheeks flush when she thanks him for a cappuccino.
Chung is 24, with a deep, clipped voice that rises to a Californian drawl when she's joking. She's the Kate Moss of teen TV - effortless, elegantly edgy, and one of the few female presenters who hasn't got naked for a men's magazine. Born in Hampshire to a Chinese father and English mother, Chung, the youngest of four, was scouted by Storm models at the Reading Festival aged 15. 'I was there following round a local band called Caretaker. I have a disturbing history of following bands around don't I?' She grins, glancing at her phone for messages from her boyfriend of the past year, Arctic Monkeys' frontman Alex Turner. The pair are spotted, nightly, snogging at fashion parties.
After three years of modelling for catalogues ('there was lots of money to be made'), teen magazines, and pop videos for The Streets and Holly Valance, she auditioned for a presenting job on Channel 4. 'If I bump into the models who I used to work with they congratulate me on getting out of the industry, but I always felt like something was going to happen, that I'd be plucked out...' When Simon Amstell and Miquita Oliver left Popworld, Channel 4's sarcastic Saturday-morning music show, Chung was invited to co-present.
'I didn't really want to be a presenter, because I thought it was even less of a career than a model, but then I went on to have the best year of my life. We were encouraged to be quite nasty to interviewees.' While 'it wasn't what you'd call a cosy takeover, and I was prepared for everyone to hate me', she was unexpectedly great, correcting rock stars' grammar and helping Paul McCartney compose a song about shoes.
Popworld ended last summer. Chung got the call telling her it had been decommissioned when she was in make-up, having a fake moustache applied before she interviewed an emo band. 'I hung up on my agent,' she says, 'and just went away and cried and cried.'
After a slot co-hosting Ben Elton's regrettable ITV series Get a Grip, Channel 4 hurried her into a presenting job on reality show Vanity Lair, where contestants were evicted from a mansion for being too ugly. At the mention of the show, Chung raises her eyebrows, indicating embarrassment. It's odd then, with such trash on her CV, that she's universally acknowledged to be properly cool. Alexa Chung is cool despite her TV letdowns. Her confidence and her style - the grubby band T-shirts matched with aspirational PPQ-does-Chanel cardigans, loafers and a vintage satchel - inspire Heat readers and fashion editors alike. It's unsurprising, then, that her latest TV gig is a fashion show, which she presents with Gok Wan, and which she describes as 'pretty much my dream job'. Gok's Fashion Fix sees Chung flying around the world interviewing designers and asking such serious fashion questions as, 'Will your boobs fall out of this season's cut-out swimsuits?' Spoiler alert: yes. Yes they will.
She's having a bit of trouble with fame. 'When I realised that I was famous, it occurred to me that fame doesn't really exist any more. And then I went to Selfridges and saw Mariah Carey, and realised that it was still very much alive.' (And wearing a visible diamanté thong.) 'I don't really want to be recognised for presenting, or for wearing clothes,' she says. 'Also, when you're famous, you have to be polite all day. So when someone asks for your photo, that's the only time they've done it that day, but for me it's the 15th time, and I might say no, and then they'll think I'm a b*tch.'
We go back to the 'least sexy person in the world' thing. She's fuming because Loaded recently printed some old pictures of her in pants. 'I don't want to look sexy in photographs. I think it's an easy option. I'm so sick of girls pushing their boobs up in Myspace photographs. I hate the way women want to be "hot" all the time. And I'm on youth TV, so I'd like to try and be a different kind of role model,' she raises her chin slightly. 'One who's properly covered up.'
