The BBC radio presenter was pictured out in public with his wife, Natasha Shishmanian, and their two sons, Eli and eight-year-old Noah.
Eli looked adorable in a green metallic dress, white socks and black trainers.
Twitter account Liberty GB, a UK political party, shared photos of the family and wrote: “What is it with these celebrities making their little boys wear dresses?”
Some people replied to the tweet agreeing.
Fortunately, some people who saw the tweet defended the five-year-old.
One person wrote: “Why is your son in a dress that is just weird?!”
However someone replied: “So what if he wears a dress? If a boy wants to wear ‘girl clothes’, so be it. In many cultures, men wear skirts and dresses. Why is it so different in a situation like this?”
