Brad Pitt took his twins Knox and Vivienne for a pottery painting in London, PEOPLE reported on Monday. The 52-year-old "Fight Club" actor enjoyed an artistic day out with his two youngest children in London on Saturday.

Pitt is currently in the British capital to film his latest and yet to be named World War II spy drama film with Marion Cotillard. He took his kids out for a pottery painting treat under the cold English winter sunshine. The father of six even picked up his own brush to create his own art along with his children.

"It was just Brad and the twins doing the painting together. They were in the pottery café for a couple of hours and seemed to have a lovely time. They were very happy," a source told PEOPLE regarding the excursion before the U.K. celebrated Mothers' Day. "It wasn't a Mother's Day thing. Knox and Vivienne painted a few things and then Brad painted a few things himself. It was just a fun day out with Dad."

On the same day, Pitt was also spotted walking with the twins and his other child Maddox around West London. The Cambodian born, who is 14-years-old, has recently been helping mother Angelina Jolie-Pitt with some research work for the real-life Cambodian drama "First They Killed My Father", which Jolie-Pitt has co-written and as well as produced and directed. The 12-year-old Vietnamese-born, Pax, also took on the role as the set photographer for their mother's upcoming film which is based on the memoir of Loung Ung - a Cambodian author who is also a human rights activist and lecturer.

Despite the endless rumors that keep on circulating about the A-list couple's divorce, "Brangelina" keep on slamming the gossipers by staying together and even getting almost-matching tattoos while in Cambodia that represent health.
