Her Majesty Queen Elizabeth II turns 90 today and big celebrations are being held across London to honour the important birthday. To mark the occasion, we've made a list of all the amazing Guinness World Records titles held by the much-loved monarch:
1. Longest reigning queen
As of 9 September 2015, Elizabeth's reign exceeded the rule of her predecessor Queen Victoria, which had lasted an incredible 63 years, seven months and three days from 20 June 1837 to 22 January 1901. Elizabeth II was born on 21 April 1926 and took to the throne on 6 February 1952 following the death of her father, King George VI.
2. Oldest current monarch
Her Royal Highness is the oldest current monarch. The previous record holder His Majesty King Abdullah Bin Abdulaziz Al Saud of Saudi Arabia, sadly died last year, aged 90. The Queen is also the oldest British monarch ever as she has reigned longer than King George III (1760-1820), who was King until the age of 82.
3. Most currencies featuring the same individual
The image of Elizabeth II appears on the coinage of at least 35 different countries - more countries than any other living monarch. Can you name any of them?
4. Wealthiest Queen
In April 2012, the Sunday Times estimated the wealth of Her Majesty at a mind-boggling £310 million ($504 million). Fine art, jewellery and property in England and Scotland account for just some of the Queen's huge personal fortune.
