The Duke of Cambridge enjoyed a special day Sunday and it wasn’t only because of Father’s Day. Sunday also marked the prince’s birthday. 

Prince William turned 33 and celebrated his second Father’s Day with new baby Princess Charlotte and nearly 2-year-old Prince George.  Although the palace said only the day would be spent “privately,” People reported Saturday, media speculated the prince likely would get a personalized birthday card from wife Kate and Prince George.

The duchess previously revealed how she and young George enjoyed painting together. She spoke about painting with her son during a visit at the Ben Ainslie Racing Center in Portsmouth in February where she and 72 school children helped to complete a sailing mural. The Mirror UK reported Kate told art teacher James Waterfield of the Park Community School George is already showing a passion for art. "She told me she was painting yesterday with baby George and she should have brought him down because he loves doing all of this," Waterfield said.

The royal family’s private Father’s Day celebration is a stark contrast to how they the previous weekend was spent, attending the annual Trooping of the Colors ceremony where Prince George had his first Buckingham Palace balcony appearance while wearing the same clothes his father wore years before, and a charity polo match in Gloucestershire. Hello magazine even reported how royal watchers still remember Prince William spending his first Father’s Day participating in the same charity polo match with then 11-month-old George and Kate Middleton. Prince George was as adorable and playful as before, playing with his mother on the grass while his father joined the charity match.

Meanwhile, Kate Middleton’s parents, Carole and Michael Middleton, celebrated their 35th wedding anniversary Sunday, though it’s not known if the two families spent the day together.
