Charlotte spreads her wings

It used to be the voice that guaranteed her centre stage. But these days, it seems, Charlotte Church is determined to make an impact without singing a note.

While her transformation from angelic choirgirl to vampish teenager has been well-charted, her latest incarnation appears to represent a spectacular step towards womanhood.

In a diaphanous floralprint summer dress split at the midriff, she floated into the Louis Vuitton Classic Car and Bike event and stole the show from the sort of celebrities who would normally have expected to attract the attention of photographers, including model Penny Lancaster.

One guest said: 'Charlotte looked sensational. She was showing off a lot of flesh and looked very sexy.

'There was one moment when the sun was shining through the back of her dress showing off her figure like the famous picture of Princess Diana.'

Miss Church launched her

singing career at the age of 11 and has accumulated a personal fortune of £5.5million, which she was handed control over when she turned 18 earlier this year.

She has been re-inventing herself in recent months as she prepares to showcase a new style of music in the autumn.

With regular gym workouts she has lost a stone and half and has been taking expert advice on her wardrobe.

A source close to the star said: 'Charlotte has been working very hard on her image and is in the best shape of her life.

' Although she has lost weight, she is still curvy and looks great. She is very much looking forward to launching her new album later this year.'

She was accompanied to the Louis Vuitton event, at Waddesdon Manor in Buckinghamshire, by her boyfriend Kyle Johnson, 19, a trainee hotel manager who took the place of model Stephen Johnson earlier this year.
