Nicola Henshall, a charming, big-eyed 19-year-old from Stoke on Trent, plays a peasant in Giselle and a gypsy girl in The Snow Queen. Laurretta Summerscales, 17, tells me she is playing 'mice and cheese' in The Nutcracker, and she also has two roles in Giselle: 'a villager, and one of the willies.' The willies? 'They're like spirits.' As in, gives me the willies? 'Yes!' Brimming with shy excitement, Laurretta, 17, is the baby of the company, recruited a year early from the English National Ballet School by artistic director Wayne Eagling, who spotted her exuberant promise. 'I love jumping and pirouettes. I'm not very neat; I just go for it!' She grew up in Woodham, Surrey, and attended her mother's modern dance school, but always secretly preferred the stricter discipline of ballet. This month will see her debut at the Coliseum. 'It will be the first time I've ever stepped on the stage,' she says.
