England cricket legend Ian Botham collected his knighthood from the Queen and said the occasion at Buckingham Palace was "mind blowing".
Sir Ian Botham has raised millions for Leukaemia Research
Botham, 51, admitted to being nervous despite having met the Queen before.
He said: "I've admired the Queen for many years, been lucky enough to have met her at a few occasions, but today was the icing on the cake.
"I've had some great moments in sport and other walks of life but nothing matches this."
Sir Ian, nicknamed Beefy, finished his career as England's leading Test wicket-taker with 383 victims and more than 5000 Test runs.
He has also raised millions for Leukaemia Research, embarking on a host of long-distance charity walks including from John O'Groats to Land's End.
He was honoured for his services to cricket and charity.
"It's not just for myself but for my family and for the leukaemia people who give their time to work for me," he said of his award.
"It's just a very special day and one that I will never forget."
Sir Ian was joined by his wife Kath and grandchildren Regan, 13, and nine-year-old James.
The family were celebrating with a special reception at Lord's.
Sir Ian is planning a new charity walk next October when he will make his way around up to 18 UK cities.
