Sam, who is representing his charity Love Your Sister on the show, danced a contemporary with his partner Georgia.
The theme of the night was “memorable year” and the 41-year-old had chosen 2017, the year Connie passed away after years of living with cancer.
The actor said before the dance that he wanted to tell their “whole life story in one dance” and afterwards thought he’d done just that.
From the moment Georgia, dancing as a spirit version of Connie, started pushing Sam on a swing as the opening notes to ‘See You Again’ played many people lost it.
Viewers expressed how moved they were on Twitter.
Aaaand I’m sobbing. My heart hurts so much for Sam but I know Connie was watching that
