Following the birth if the royal baby Prince George, the Duke and Duchess of Cambridge, Prince William and Kate Middleton have been spending all of their time with their baby boy. However, on Saturday the Prince decided to make his first public appearance since leaving the hospital with his wife and son.

Prince William joined his brother Prince Harry for a charity match at Ascot, Berks, according to the Mirror UK.

The royal was spotted wearing white jeans paired with a blue shirt and red and white Adidas.

Although out for a polo match Prince William was clearly still in daddy mode as he jokingly asked if his prize for winning would be nappies (the British nickname for diapers) confessing, "I've got to pick some up on my way home."

Although happy to have a baby boy, the Duke of Cambridge admitted it was "good to get out of the house" for an afternoon.

However, while meeting guests afterwards, he said, "I've got to make sure I'm not too late back."

When reflecting on his polo performance Prince William said, "I was in baby mode out there, thinking about nappies, I wasn't really in the zone."

He also revealed a little fact about his son Prince George and said, "He likes to move around a lot, he wriggles a lot."
