Another rumoured relationship for Holland was with fellow actor Ella Purnell, with whom he got pretty cosy at the BAFTA afterparty in February 2017. According to The Sun, the two were attached at the hip following the event (where Holland won the rising star award) and may have even left together.
A source claimed, "Tom and Ella were very close inside the Weinstein party and it looked really obvious that he was taken by her," noting he was "leading her around the dance floor by the hand." Nothing more was ever heard about this maybe-couple after the party, so it may have been a one-night romance.
