The Queen and Sir David Attenborough, both 96, are two of the UK's most-loved national treasures.
Born just weeks apart in 1926, the pair hold a special place in the hearts of many and have worked closely together during their shared decades in the public eye.
Attenborough made his first television appearance just a year after the Queen's Coronation, taking to the small screen in 1954 with the BBC documentary Zoo Quest.
