Sienna steps in at carol service

As understudies go, she wasn't a bad choice. Sienna Miller, soon to be seen opposite her real-life boyfriend Jude Law in the remake of the film Alfie, stepped in at the last minute to help a charity carol service at St Luke's Church, Chelsea.

Other readings came from Bill Nighy - another Love Actually star, who called the service 'wonderful' - and actress Emily Mortimer, who gave a reading from The Power of Compassion by the Dalai Lama.

Annie Lennox and her daughters joined in the carols.

The opera group Amici Forever performed Whisper Of Angels, based on Faure's Pavane, and Prayer In The Night, based on Handel's Sarabande.

Proceeds from the concert go to Nordoff-Robbins Music Therapy, which uses music to treat suffering in children and adults.
