She has been in the news in recent times for her campaign to be the next Governor of New York, but Cynthia Nixon's latest Instagram post has taken a more personal slant.

The 'Sex and the City' star took to the social media platform to congratulate her son Samuel (Seph) - who was previously known as Samantha, but who has come out as transgender - on his graduation earlier this month.

Nixon posted the photo of the 21-year-old's graduation on Trans Day of Action, saluting him for both his academic achievement and for marking the occasion, saying that she was "so proud" of him:

Nixon has one other son, Charles, with her former husband Danny Mozes, as well as a son, Max, with her current partner Christine Marioni.
