Kate Moss has said she is "devastated" over the death of Alexander McQueen.
The supermodel released a statement after hearing the designer - whose real name was Lee McQueen - was found dead at his home.
The statement read: "Kate is shocked and devastated at the tragic loss of her dear friend Lee McQueen - her thoughts are with his family at this sad time."
Designers Vivienne Westwood and Matthew Williamson also paid tribute.
Vivienne was "incredibly sorry" to hear the news, a spokesman said, while fellow designer Matthew commented: "I am shocked and deeply saddened by McQueen's death - he was a genius and his talent was second to none."
He went on: "Like many others, I always cited him as a hugely inspirational leader of world fashion - he will be greatly missed."
Alexandra Shulman, editor of British Vogue, said: "His death is the hugest loss to anyone who knew him and for very many who didn't."
His design company, also called Alexander McQueen, said in a statement: "At this stage it is inappropriate to comment on this tragic news beyond saying that we are devastated and are sharing a sense of shock and grief with Lee's family.
"Lee's family has asked for privacy in order to come to terms with this terrible news and we hope the media will respect this."
A spokeswoman for the British Fashion Council said: "We are deeply saddened at the news of Alexander McQueen's untimely death. He was a unique talent and one of the world's greatest designers. Our thoughts are with his friends and family at this sad time."
