On Thursday evening fun dad Guy, eight-year-old Rocco – who bears a strong resemblance to his director dad - and David, three, made the most of a warm summer evening by attending a theatre production in Kensington Gardens.
The trio were joined by friends to watch family favourite Peter Pan, transported to Neverland inside the specially commissioned state-of-the-art Theatre Pavillion, which Charles and Camilla opened last week.
Being taken back to his childhood, and spending time with his own children, evidently put the 40-year-old in a playful mood. Swinging his youngest up onto his shoulders as they walked to and from the venue, Guy cheekily pinched sweets from David and Rocco, who were more than happy to let their dad dip his hand into their pick'n'mix.
Meanwhile his New York-based ex-wife has been working hard to integrate four-year-old Mercy into the family since her arrival in Britain. The 50-year-old pop star – whose new boyfriend Jesus Luz has been spotted cycling near her £15 million Mayfair home – is said to be determined not to "smother" the little Malawian girl with attention.
"Madonna has been waiting for this moment for years, but realises that she shouldn't over-stimulate Mercy by immediately smothering her with attention and things to do. After all, she has been in this before when she brought David home from Malawi so she understands how confusing it must be," a source has said.
