As Monaco's Princess Caroline supported her long-time friend Chanel chief designer Karl Lagerfeld at a fashion launch this week, she had another less pleasant matter on her mind.
The royal – who looked as elegant as ever in a delicate pastel ensemble from the brand's Spring 2012 line at the inauguration of a jewellery collection – may have been thinking about her son Pierre Casiraghi's legal problems.
He has filed a civil suit over a nightclub brawl that took place in February.

Pierre – who was left with cuts to his face after the scuffle – is suing 47-year-old businessman Adam Hock, whom he claims drunkenly attacked him and his friends after joining their table at New York's Double Seven club.
The fracas apparently broke out over a bottle of vodka that Adam was sharing with models Natasha Poly, Valentina Zalyaeva and Anja Rubik.
In his lawsuit, Pierre, below left with his siblings Andrea and Charlotte, describes Mr Hock as drunk and "pugilistic", claiming the club shouldn't have served him alcohol.
He also claims his assaliant and his defense lawyer, Joseph Tacopina, defamed him by saying he was responsible for the fight and that the Monegasque royal had a history of causing trouble in social situations.
Mr Tacopina defended his position, saying: "If they don't like the truth, that's their problem."
Representatives for the club Double Seven also intend to dispute Pierre's damages claims.
Owner Jeffrey Jah "intends to vigorously defend against them and is confident that he will ultimately prevail," his lawyer Terrence Oved said.
