In December 2017, Hamilton courted controversy after sharing a video on Instagram of his nephew wearing a princess dress in which he commented "Why did you ask for a princess dress for Christmas, boys don't wear princess dresses". He was condemned on social media and by LGBT charities for his comments. He subsequently deleted the video before later deleting all content from his social media channels, though he returned to actively using his social media accounts on 17 January 2018. Hamilton apologised for his comments, and later appeared at Disneyland Paris with his nephew, who wore a princess dress for the trip, as well as featuring on the front cover of GQ wearing a rainbow tartan kilt he designed with Tommy Hilfiger, saying "I've done something and then realised the effect I've had ... I want to make amends. I accept it, realise it and I'm glad that I'm accountable for it".
