Monaco's adorable royal twins have stolen the show at the principality's end of summer picnic.
Dressed in traditional costumes, Prince Jacques and Princess Gabriella, 3, accompanied parents Prince Albert and Princess Charlene to the festival.
The end of summer picnic, or the 'U Cavagnëtu', is a Monagasque-style picnic open to all in Monaco’s Princess Antoinette park. It has also become a benchmark occasion for royal watchers.
A resident told PEOPLE, 'They’ve grown so much over the summer.
'What’s truly amazing, really special, to see is how attached they are to one another. How attentive Princess Gabriella is to her brother.'
