A London Ambulance Service spokesman said: ''We were called at 15.53 to reports of a road traffic collision involving a car and a bike on York Way.
''We sent a responder by car and an ambulance crew to the scene. We treated a boy reported to be 16 years old for a shoulder injury. He was taken to University College Hospital.''
A witness had dialled emergency services to the scene. Billie - who is married to actor Laurence Fox - was questioned by police before being allowed to continue on her way to perform in the play 'Great Britain' at the National Theatre. However, she was so shaken by the incident, her understudy, Jo Dockery, took her role that night instead.
