Performing the second “Couples’ Choice” dance, Charles and Karen wowed the judges with their contemporary Street Dance.
Yet as the scores rolled in, the pair were left completely dumbstruck and the rest of the professional dancers raced in to share in their joy.
But many viewers were most shocked when Stacey Dooley’s dance partner and Karen’s wife Kevin jumped over a stool to give his ex-wife a big hug.
The pair were clearly emotional as they held onto each other, and Karen couldn’t resist grinning at him.
As the moment came to an end, Karen then embraced her friends and colleagues Neil Jones and Oti Mabuse too, and it was smiles all around.
Taking to Twitter, viewers couldn’t hide their feelings on the unfolding events.
One person declared: “I love Kevin so much, just watched him clamber over furniture to get to Karen- ‘LET ME HUG MY WIFE I MUST CONGRATULATE MY SOULMATE’. #Strictly #ItTakesTwo #wherecanIgetaKevin.”
“AWWW KEVIN GAVE KAREN A HUG! I am fully here for public displays of affection. #strictly,” another shared.
A third agreed: “aww nice to see Kevin congratulate Karen on her dance with Charles #strictly.”
“Seeing Karen and Kevin hug breaks my heart #Strictly,” a fourth then admitted.
Fans were also elated for Charles and Karen’s performance tonight, who have been disappointingly in the bottom two two weeks in a row.
One person insisted: “If Charles and Karen are in the dance off again, then I actually don’t know what the f**k is wrong with people #strictly.”
“Best dance of the series!!!!!!! Great work @ChuckyVenn @karen_hauer!! #strictly,” another noted.
A third said: “Great to see those scores for @ChuckyVenn & @karen_hauer and to see more recognition for how good they are #strictly.”
“Loved how all (most) of the pro dancers were SO pleased for Karen when they finally got a great score, including Kevin. Great to see. #Strictly #strictly2018,” another fan added.
Following the judges’ scores, Karen was so shocked at first she fell to the ground.
Taken-aback in the moment, Charles and presenter Claudia Winkleman were forced to pick up the dancer as she seemed ready to give up in shock.
