Now this is what you call an A-list playdate!
In between preparations for the Country to Country music event at London's O2 arena, the family of five found time to pay a visit to Chris Martin's home.
Despite chilly weather outside, the families took a stroll on Hampstead Heath. Apparently enjoying the brisk, fresh air, the kids walked Martin's dog and later stopped at a nearby playground.
With the proud parents looking on, the kids were laughing and smiling as they played on the swings and raced down the slides.
Sounds like a successful playdate to us!
