Nicholas has never confirmed the speculation if he is gay or not.
But the actor revealed that his love for acting was initiated when he wanted to impress a girl very much, and he did a whole festival to make her notice him. He told the Wonderland Magazine that he performed at the Edinburgh Festival to impress a girl he fancied and returned with an acting agency.
Even if his relationship with the girl might not be successful, Galitzine found a new passion for himself and had landed himself the role of Prince Charming in the Amazon Prine reboot of Cinderella.
