Campbell still nervous backstage
Naomi Campbell says she still gets nervous backstage at fashion shows, while fellow supermodel Erin O'Connor admits she practises her catwalk style in the supermarket.
The pair are co-stars, along with Swedish model Caroline Winberg, in new show The Face.
The first episode of the Sky Living show sees 24 girls whittled down to 12 and put in three teams of four each mentored by the one of the trio.
The girl judged to be the eventual winner gets a contract with Max Factor.
Naomi, who is famous for her fiery temper, admitted she was "a drill sergeant" with her girls but insisted it was "tough love".
She said: "I'm not actually very confident right before I walk on the runaway, like last week in New York and the week before I crossed myself, I'm nervous backstage because anything can happen.
"It's live, I've had a fall, I've lost a skirt, I've had a top fall off".
Erin, who said her "tallness" meant the girls on her team "can come in for a cuddle", said she still practised her catwalk style.
She said: "I end up doing it in the supermarket sometimes with my trolley and all of a sudden I realise I'm in the centre aisle of the frozen food section and then I think where's it gone, where's my shopping?"
The second episode of the series sees the would-be models pose with a shopping trolley and rubber chicken for a trendy magazine before one is kicked off the show.
Naomi, who said her mother had been her mentor, said: "My mother used to teach me how to walk the runway down the passage and the steps to Lionel Richie."
Earlier this month, she accused fashion designers of snubbing black and Asian models on the catwalk.
But speaking at Thursday's launch, which was hosted by Nick Grimshaw in Covent Garden's Royal Opera House, she praised recent shows which had used "women of colour" and said it must not become "a trend".
She said: "It's not something that's just here for five minutes and I hope it's not the situation of everyone going out to grab a model of colour or an Asian model because we are raising our voices".
