It's been 14 years since the now Prince and Princess of Wales announced their engagement, but there's one name he called his wife-to-be that he never uses now.

Kate wore her famed sapphire engagement ring during a slate of engagements for the annual Festival of Remembrance.

In March, Kate confirmed she had been diagnosed with an unknown form of cancer. What followed was a nine-month battle as she underwent “preventative chemotherapy”. She endured intense online speculation in the weeks leading up to the public announcement and has largely stayed out of the spotlight since.
