We simply can't get enough of Monaco's adorable three-year-old twins Prince Jacques and Princess Gabriella.
The blonde tots accompanied their parents Prince Albert and Princess Charlene to the town's end of summer picnic, dressed in traditional costume.
Gabriella wore a stunning candy stripe skirt with an embroidered apron with flowers along with a traditional waistcoat while her brother wore a cute pair of camel trousers and matching embroidered waistcoat.
The children were in a great mood and onlookers noticed how well they enjoyed the two hour attendance.
"[It] was a very, very, very beautiful evening," one attendee told PEOPLE. "The children clearly enjoyed themselves with their cousins around them and, the music and food."
"They've grown so much over the summer," noted another. "What's truly amazing, really special, to see is how attached they are to one another. How attentive Princess Gabriella is to her brother."
The family have recently returned from a vacation in Tahiti where reportedly Lady Gaga taught Gabriella some dance moves!
The singer and the royal toddler were attending a beach party at the luxury Brando resort and the pair were spotted dancing the night away along with Gabriella's mother Charlene.
In an interview with French Magazine Point de Vue, the princess discussed how much energy her little ones have.
"There are mornings where they sleep a little later than usual and those where they wake up much earlier," she said.
"At age 3 1/2, they're so full of life, to the point that they sometimes seem to me to have too much energy for their age."
She also mentioned how the twins got on together.
"We discover them even closer accomplices than we imagined," Princess Charlene said.
"Jacques is very reserved. He is sure of himself, but he likes to take his time doing things, to observe them, and no one can force him to do anything."
