Prince William catches out royal fan trying to take selfie with him

'I know what you are doing, you are taking selfies'

The Duke of Cambridge caught out an eager royal fan who tried to snap a sly selfie during a visit to Northern Ireland.

Along with the Duchess of Cambridge, Prince William visited the government residence of Hillsborough Castle on Tuesday for its annual garden party.

One guest, Portrush resident Anne Hyndman, 62, was so eager to get a picture of the Prince that she attempted to catch him unaware in a selfie.

However, it didn’t quite go to plan.

“He saw me taking selfies,” Mrs Hyndman told the Press Association. “He said ‘I know what you are doing, you are taking selfies – I can see you out of the side of my eye.’”

If Mrs Hyndman thought their exchange over, she was wrong. The Duke spotted her again later on and began chatting about his surprise that selfies are popular among virtually every demographic.

“He came back up and I was taking photos again and he said ‘That’s the woman with the selfies – that’s a young one’s thing, now you’re at it.’"

It seems the exchange with the 33-year-old Prince only added to Mrs Hyndman's day out with her husband: “it was just the best day we ever had."

Royal selfies can be a rare find. Two Australian hockey players made headlines when the unsuspecting Queen ‘photobombed’ their selfie at the 2014 Commonwealth Games in Glasgow.
