The Queen met a series of diabetes sufferers - including the teenage daughter of a Premier League football boss - at a reception to mark a charity's 80th birthday, Daily Mail reported.
Liverpool manager Brendan Rodgers, his child Mischa, 19, and Genesis guitarist Mike Rutherford were among those attending the event for Diabetes UK at St James's Palace in central London.
Rutherford also has a child who suffers from Type 1 diabetes - and both stars lend their support to the cause to raise awareness for the disease. Mischa has had the disease since she was seven.
Former Swansea City manager Rodgers said: 'An event like this shows the seriousness of diabetes - if someone like the Queen is patron of the charity and is celebrating the work at that it does.'
At the end of reception the Queen, dressed in a duck-egg blue silk evening suit, was presented with a posy by eight-year-old Amber Clayton, who was just six when she found out she had diabetes.
Speaking shortly before the presentation a nervous Amber said: 'Is this a dream, or is this real?'
Mischa said the charity had been a great support to her and that in the 12 years she had lived with diabetes, there had been great advances in treatment.
'I have now got cousins around me who are seven years old. It is only when you look at them that you realise they are babies.
'They are so young, and so to try and get your head around it, is quite a big thing. It makes you realise how young I was.'
Rodgers said: 'My role is to support, firstly Mischa. And she has been incredible as a young lady being diagnosed.
'And then to be able to support the charity is a great honour, and it is a complete honour and privilege to be here tonight.'
The Queen met a number of people at the reception, taking a short time to speak with them and find out about their involvement with the charity.
Rutherford said he had been spoken to about his youngest son Harry, now 27, who was diagnosed with diabetes 15 years ago.
'I have worked with the charity for a while and the more I can do to promote it, the better. It does such great work.'
Amber, wearing a sparkly pink dress that was bought specially for the occasion, said meeting the Queen had been a 'weird' experience.
She added: 'I have been very excited and it has been making me feel a little bit sick.'
Simon O'Neill, Diabetes UK's director of health intelligence, said: 'This event marks our 80th anniversary and it is wonderful to celebrate the important work of the charity and all our achievements so far for people with diabetes.
'Diabetes affects millions of people in the UK and we are delighted that our patron, Her Majesty The Queen, was able to attend the reception at St James's Palace to meet so many of our committed volunteers and supporters.'
