Prince Christian of Denmark has proven to be the most eligible bachelor in Europe - with Princess Maria Chiara and commoner Anne-Sofie Tornso Olesen fighting for him.
Prince Christian, the heir to the Danish throne turns 18 this weekend - and will celebrate the milestone birthday with a lavish gala at Christiansborg Palace in Copenhagen.
The Italian heiress, 20, is enjoying her summer holiday alongside her sister Princess Maria Chiara, 18, who is thought to be dating Prince Christian, the 17-year-old heir to the Danish throne.
Speculation on whether the two were dating began in May when a group photo emerged on social media of the duo standing close together at the Monaco Grand Prix.
Princess Chiara of Bourbon-Two Sicilies showed off her toned midriff during a sun-soaked evening in St Tropez. The Italian heiress is enjoying a sun-soaked getaway to the south of France.
