Oscar-winning actress Dame Maggie Smith died in hospital this morning aged 89.
The British star was known for prominent roles in Harry Potter and Downton Abbey, and her Academy Award-winning performance in The Prime Of Miss Jean Brodie.
Her children, Widow Clicquot actor Chris Larkin, and Die Another Day star Toby Stephens, announced her death in a statement issued this afternoon.
They said: 'It is with great sadness we have to announce the death of Dame Maggie Smith. She passed away peacefully in hospital early this morning, Friday 27th September.
'An intensely private person, she was with friends and family at the end. She leaves two sons and five loving grandchildren who are devastated by the loss of their extraordinary mother and grandmother.

'We would like to take this opportunity to thank the wonderful staff at the Chelsea and Westminster Hospital for their care and unstinting kindness during her final days.
'We thank you for all your kind messages and support and ask that you respect our privacy at this time.'
Born in Ilford, Essex, on December 28, 1934, she was an internationally recognised actress for much of her life after playing the fanatical teacher Jean Brodie in The Prime Of Miss Jean Brodie.
She also won over Harry Potter fans later in life, when she appeared in the film series as the quick-witted, kind and formidable Professor McGonagall.
And in 2010 she was central to the success of ITV series Downton Abbey, in her Emmy-award winning role as the acerbic Violet Crawley, Dowager Countess of Grantham, which she continued to play in the films.
Among the first to pay tribute was her friend Gyles Brandreth , who said: 'The saddest news: the death of Dame Maggie Smith marks the end of a golden era and a quite extraordinary life.
'She was a truly great actress, 'one of the greats' and simply the best company: wise, witty, waspish, wonderful. One of a kind in every way and consequently irreplaceable.'
