Kate Middleton might well be having a few stern words with her younger brother James.
A set of pictures have emerged of the 26-year-old socialite that might prove somewhat embarrassing for the Duchess.
The fun images may well show the younger Middleton sibling's sense of fun and tomfoolery, and while it's not dissimilar to the kind of antics Prince Harry is known for, it might not go down so well with the royal in-laws.
Prince Harry was famously photographed at a fancy dress party in a Nazi costume, for which he later apologised.
Last year he was reportedly chastised by the Queen for his naked antics in Las Vegas when he was caught on camera cavorting with a blonde holiday-maker.
James, who is dating former MTV host Donna Air, runs a successful baking company called Nice Cakes.
