King Charles and Queen Consort Camilla will be crowned in a joint coronation ceremony at Westminster Abbey on 6 May.
The historic occasion comes less than a month after the couple celebrated their 18th wedding anniversary.
Charles and Camilla have known one another since 1970, and regularly met at polo matches over the years.
WATCH: King Charles III in profile Camilla subsequently married cavalry officer Andrew Parker Bowles in 1973, and Charles married the former Lady Diana Spencer in 1981 – but at some point in the 1980s, their romance resumed.
In 1994, Charles confessed to adultery in a TV interview with broadcaster Jonathan Dimbleby, but only after his marriage had "irretrievably broken down".
Camilla accompanied Charles to many of his public engagements in the years leading up to their engagement in February 2005 and subsequent wedding in April that year.
With less than two weeks until the big day, HELLO! is taking a look back at Charles and Camilla's milestone moments together…
