James Middleton is the handsome younger brother of the Duchess of Cambridge but little is known about the 27-year-old.
While Kate's beardy-brother was spotted in the royal box at Wimbledon recently with sister Pippa, he has mostly heeded palace advice and chosen to keep a low profile.
James – who reportedly lives in a £1m flat in Chelsea with Pippa – works as a budding entrepreneur and owns a do-it-yourself cake-making business called the Cake Kit Company.
In the past Middleton has had a few rumoured high profile romances and he's currently dating TV personality, Donna Air but since the pair began their relationship James seems extra cautious about his privacy.
Unfortunately for James his choice to shun the spotlight only adds to his shadowy allure and the possibility of his sister becoming Queen cements his status as a person of interest. We have compiled a gallery to try and get to know the mysterious Mr Middleton.
