Princess Diana's niece, Lady Kitty Spencer, has caught the public's attention in recent weeks after appearing in Tatler's December 2015 issue and posting bikini photos on Instagram.

But unlike her prim and proper contemporaries (such as the Duchess of Cambridge), 24-year-old Spencer has raised "aristocratic eyebrows" around her "racy" bikini pictures, Page Six reports. Lady Kitty is represented by Paula Karaiskos of Storm Model Management (Kate Moss' agency), parties with London's elite and has a few friends on the Brit reality show Made in Chelsea.

The royal socialite is the eldest daughter of former model Victoria Aitken and Earl Charles Spencer, Diana's brother. Lady Kitty first turned heads with her sisters in 2011 at Prince William's wedding. As for now, The Daily Mail reports, "She is really enjoying being the centre of attention."
