The Duchess of Cambridge, née Kate Middleton, was spotted playing with Prince George in Holland Park on Sunday
The Duchess of Cambridge and Prince George enjoyed some quality mother-son time together at the weekend. Kate was spotted in London's Holland Park on Sunday, energetically entertaining her son with a fun monster-inspired game – in spite of the rainy weather.
An onlooker confirmed to HELLO! Online that at around 10am on the "wet morning", Kate and George were enthusically making use of the play area in the London park – and with no one else around, the duo got stuck into their game.
George was "really smiling and laughing" as his mother "chased him, waving her arms around pretending to be a monster," said the source. "It reminded me of the film Monsters Inc.
"They were running around on the rides, the swings, roundabouts and slides," added the onlooker. "They were on their own. Just the two of them."

The Duchess and her son, who were accompanied by two royal protection officers, were suitably dressed for the outing, wearing: "matching waxed-green coats, dark jeans and boots."
The Cambridges are currently residing in the capital, having spent several weeks at their country home Anmer Hall following the birth of Princess Charlotte. It is thought that the family-of-four relocated once Prince William's paternity leave ended at the beginning of the month.
Royal watchers have speculated that the Duchess and her 22-month-old son will stay in London to make an appearance at Trooping the Colour, which takes place on Saturday 13 June.
If Kate does attend the celebration, which is held annually in honour of the Queen's birthday, it will be her first public appearance since she presented baby Charlotte to the world on the steps of the Lindo Wing on 2 May.
Prince George will turn two on 22 July
William and Kate's London home, Kensington Palace, will be a hive of activity in the coming months.
According to the New York Post's Page Six, the royal residence will play host to Nicky Hilton and James Rothschild's fairytale wedding on 10 July.
The fashion designer and her fiancé are rumoured to be tying the knot "at the palace's Orangery in front of hundreds of guests".
The Orangery is located within Kensington Gardens and is licensed for civil weddings and allows for receptions on its terrace. It is also located next door to Prince William and Kate's apartment.
