Asked about the imminent birth of Meghan Markle and Prince Harry's first child, William offered no insight.
“I haven’t got my phone on me," he told the crowd at an event in New Zealand over the weekend. "I have no idea!"
He added: "You guys will find out before I do at this rate!"
Meghan, who is due any day now, is officially on maternity leave, while her husband, Harry, has been making last-minute appearances as he awaits the baby's arrival.
On Sunday, he cheered on runners at the London Marathon, while just days before, he joined his sister-in-law, Kate Middleton, for an Anzac Day ceremony.
