Royal watchers were quick to notice the Duke of Sussex has been sporting a black titanium ring during his tour of Australia with wife Meghan Markle.
"I thought it would be suitable because we didn't know if it was a boy or a girl and both boys and girls like bears".
Earlier that day the Duke and Duchess met locals along Government House Drive before heading into Government House for a reception hosted by the Governor of Victoria the Honourable Linda Dessau AC.
"Oh, you're going to get me in trouble", he said, per The Sydney Morning Herald. "I'm not sure I did it right!", she added.
Jerril Rechter, chief executive of VicHealth, who showed the duchess around the event, said: "She did pass an AFL football". She did a handball.
