Jessie J Domino montage video by Wed_Suc

Jessie J – the J stands for ‘whatever you want it to' – strides into the room, looking a billion dollars. After you've got past all 5'9” of her cut-glass beauty (‘I love being a giant'), her figure hugging catsuit (‘I was front of the queue for legs, back for boobs and bum'), the 36-hole Dr Martens boots and the huge gold hoop earrings with Bambi encircled in them (‘it's Disney Chic, innit?'), Jessie's superb pop star hair hits you.

A poker straight, ink black bob with a perfect fringe slashed above the eyes, it begs immediate questions. Is it inspired by historic film icon Louise Brooks? Uma Thurman in Pulp Fiction? Jessie J is pure ghetto-pop fabulosity. Her hair might just be one component part of this emerging 21st century superstar, but it's a key one. ‘To be honest, I always think of it as being a bit Mystic Meg,' chips in Jessie herself, referring to the kitsch Sunday newspaper Psychic. ‘People are always coming up to me on the street and asking me if it's a wig. I say ‘yeah, yeah, you can buy it down Hamley's''. Jessie J is also pure ghetto-pop humour.

Impossible to pin down in a world of female pop homogeneity, at 22 years of age, the future star born Jessica Cornish carries herself with the confidence of one twice her years. On the eve of her pop breakthrough, she has achieved everything herself, and on her own terms. Singer, songwriter and show-pony, she has the enviable ability to excel at it all.

She's had to. ‘Look,' she says, straight off the bat, ‘I had a minor stroke three years ago. I've got heart problems. I've looked at the big stuff straight in the eye, had people sitting on the end of a hospital bed wondering what's going to happen next and genuinely not knowing. I don't drink. I don't smoke. I can't touch drugs. I can't even have caffeine. I have to be confident. Because I can't intoxicate myself with those props ordinary young people have to give them confidence.' Amidst problems most teenagers haven't yet to even consider, music was Jessie's saviour. ‘When I'm in the studio sometimes, I think no, I don't need a therapist. I just need to write a great song.' That's when she does it.
