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!"
Any sign of the royal baby? Why doesn’t Prince William suffer from jet lag? Prince William was full of smiles this afternoon, enjoying meeting and having some friendly jokes with the NZ public as he attended a walkabout in Christchurch. #princewilliam #christchurch #royals #royalvisit #royalvisitnz #babysussex #harryandmeghan #dukeofcambridge #britishroyals #princeharry 📷 Marie Han ❤️

William also made a joke about his own experiences as a parent when asked about whether or not he was suffering from jet lag after his flight to New Zealand.
"Jet lag? What jet lag? I've got three children now, jet lag doesn't happen," he quipped, referring to his and wife Kate Middleton's adorable kids -- 5-year-old George, 3-year-old Charlotte and 1-year-old Louis.
Meanwhile, while William jet sets across the globe on a two-day trip on behalf of Queen Elizabeth, Prince Harry and Meghan are preparing to welcome their first bundle of joy. Check out the video below for all the latest royal baby news.
