The young royals were out in force for the Boodles Boxing Ball at the Grosvenor House Hotel on Saturday night.
Prince Harry and his cousins Princess Beatrice and Eugenie were spotted at the swanky event while, Hazza's girlfriend Cressida Bonas was also in attendance. However - Bonas made sure to steer clear from her royal boyf.
Even though she spent most of the evening away from her Prince Charming, at least she looked fabulous while wandering around by herself. Unfortunately Cressida was acting all shy and photographers only managed to get a snap of her sister, looking gorgeous in Sophia Kah.
Rumour has it Cressida was wearing an all-black Cavalli number, and was seen darting from the venue with close friend Princess Genie.
"Roberto thinks they are such good role models for the Cavalli brand," an insider allegedly told the Mail Online. "They can always borrow any of his dresses the life. He thinks the siblings are perfect for his image."
