Jay Harrington and Kierstan Saulter might be dating in 2021 but it has not been official if he is her boyfriend or not. 

On the occasion of Jay’s birthday on the 15th of November, Kierstan wished him on her Instagram, saying ‘that’s my man’. That is where all the news of them seeing each other began to spread. 

At first, she shared a picture with him on her Insta Story, saying Happy Birthday, and shared another one of Jay’s theme picture from the SWAT. 

Either she was trying to say ‘that’s my man’ for the character Jay has played in the series or is she really into him.

As no clue was found before this post was made about their relationship, they could be dating and have kept their relationship privately.
