PA Queen Elizabeth
In a loving gesture to her husband of 73 years, the Queen placed a handwritten note on top of the Duke of Edinburgh's coffin throughout his funeral services on Saturday. The monarch signed the note with the nickname "Lilibet" — a nickname she was given as a child.
In another heartbreaking touch, Philip is thought to be the last person who called by her childhood moniker.
The palace would not comment on the personal detail as it's "private."
During the funeral, the monarch mourned her husband, sitting alone in the pews of St. George's Chapel.

In keeping with pandemic guidelines, the Queen and members of the congregation wore face masks and sat six feet apart. Sitting inside the chapel, the Queen could be seen with her face down, only the top of her black hat visible.

Amid reports that the 94-year-old monarch will be accompanied by family members at future engagements, a former senior aide at the palace told PEOPLE, "Her family will step up and be by her side, but she will carry on. She understands that she has a job to do, and [Philip] would have wanted her to crack on. She did do so when he retired from public life."
"She will never abdicate because of duty and honor and public service is so deep in her, as it was for him," added a close royal insider.
