Surprised Strictly fans were left delighted after spotting a very familiar face supporting Kelvin Fletcher in the crowd.
The actor, 35, appeared on Emmerdale from 1996 until 2016, before quitting to become a racing driver.
And former co-star Jeff Hordley, who plays Cain Dingle on the ITV soap, showed his support by appearing in tonight's audience.
Excited fans flocked to Twitter to comment.
One wrote: "Was that Cain Dingle in the audience??? #Strictly."
While another commented: "Cain Dingle in the audience #strictly."
A third remarked: "Catching up with #Strictly and the best thing about tonights show is... Cain and Holly are in the audience!!!"
"Yes!! Not only is it the #Strictly semi final, but Cain Dingle is in the audience!!!" another wrote.
A fan tweeted: " Oooo hi Cain #Strictly #StrictlyComeDancing."
"Cain Dingle in the #Strictly audience!" one tweeted.
