While shaking hands with fans during his recent visit to New Zealand, the 36-year-old Prince was asked by a bystander about whether or not there were "any signs" of Prince Harry and Meghan Markle's baby.
Without missing a beat the jovial prince smiled and patted his jacket pocket.
"I haven’t got my phone on me," William said, in a video that captured the moment and was posted to Instagram by Marie Han of New Zealand Woman's Weekly.
"I have no idea!" he added with a laugh. "You guys will find out before I do at this rate!"
