Look at Kate Middleton and Prince William's most recent playful moments

The Spiderman suit

It made our spider sense tingle: The Duchess of Cambridge made a few jokes about buying Prince William a Spiderman costume during a recent phone call with Jason Baird, a participant in her Hold Still photography project. Jason had submitted an image of himself dressed as the superhero. Now we keep thinking of William in the classic spider suit. 

The tennis match

Prince William and Kate Middleton hit the court during their Scotland tour in late May, having learned about the Lawn Tennis Association's youth program. 

It was a competitive match. Prince William wasn't shy about his victory, claiming via Instagram, "Team Duke was the clear winner." (We wonder what Kate had to say...) 

Kate Middleton's DJ skills 

On the same tour, Will and Kate met with the Scottish Violence Reduction Unit. Kate attempted to DJ on a soundboard. The results weren't great. 

"Can rule out a music career! Keep up the incredible work Scottish Violence Reduction Unit and please do delete that music…," the Duke wrote on Instagram, under a video of Kate's performance. 

Flirting on the job

While visiting communities working with the Church of Scotland, it appears Prince William was getting very chatty with visitors—and Kate put it all on display via Instagram.

"I'm not sure who's flirting more," she captioned.
