Kate Middleton and son Prince George’s play date: more details revealed!

The Duchess of Cambridge, née Kate Middleton, visited London’s Holland Park on Sunday in order to spend time with her son Prince George. According to People magazine, who cited a witness, Kate seemed like playing a monster in their game.

“It looked like she was pretending to be a monster, flailing her arms about and chasing him,” the observer told the mag.

The onlooker added, “She was play-acting just like all mums do and he was running around loving it – he looked very happy.”

Due to less favorable weather the Duchess wore jeans, a “waxed-green coat,” and boots, and she was matched with George’s outfit.

It was Kate’s first public outing since Princess Charlotte’s birth on May 2. It is possible that her first official public appearance will be at the Queen’s birthday parade on June 13.
