Prince George and Princess Charlotte completely steal the show at royal boat race

Just when we thought they couldn't get any cuter...

Prince George and Princess Charlotte showed off their cheeky sides as they attended a boating event today.

This afternoon's King's Cup Regatta on the Isle of Wight was a big day for their parents Kate Middleton and Prince William.

The couple hosted the regatta and even took to the water themselves to compete but all eyes were on the next generation of royals.

George and Charlotte were there to cheer their parents on and certainly didn't seem fazed by the attention on them.

George, who turned six last month, was spotted on the cockpit of one of the boats, messing about in an adorable captain's hat and lifejacket.

The third in line to the British throne has no doubt been visited by the tooth fairy recently – today's photos show that he's missing even more teeth than in the birthday photos the family released in July.

Not to be outdone by her older brother, four-year-old Charlotte was later caught sticking her tongue out at photographers while her mum Kate attempted to reign her in.

Kate's parents Carole and Michael Middleton were there to mind the kids while Kate and William raced.

Prince Louis, one, clearly had the day off from royal duties as he was nowhere to be seen.
