Coronation Street fans are convinced that Adam Barlow fathered a child with newcomer Lydia.
Adam's wife Sarah Platt has developed a friendship with Lydia and finally introduced her new pal to her husband during Wednesday's episode.
When Lydia announced that she and Adam (Sam Robertson) had already met previously, Sarah (Tina O'Brien) looked shocked and Adam appeared confused.
Lydia quickly made an excuse about feeding her neighbour's cat and rushed off with her young son.
As Adam tried to play dumb and change the subject, Sarah wouldn't let it go and probed him about how he knew Lydia.
When he finally admitted that they used to date years ago, Sarah was not impressed.
"It was over 10 years ago, I was a student!" Adam told Sarah as she replied: "Come on Adam, Lydia's like the first girl crush I've ever had & she's one of your ex's, brilliant!"
Corrie fans immediately predicted that Adam is the biological father of Lydia's son, and took to Twitter to comment.
"That little lad is definitely Adam’s son! #corrie @itvcorrie," one person posted.
Another tweeted: "#Corrie Oh look. Little Adam. Another long-lost kid," while a third person claimed: "Obviously that’s Adam’s son #Corrie.
Someone else asked: "Don't tell me, Adam has got a son that he never knew about? #Corrie."
Another viewer added: "Sarah is clearly thinking that there’s history between Adam and Lydia, doesn’t take a genius to work that one out. Adam’s her sons dad. #Corrie."
Feeling sorry for Sarah, someone else wrote: "Come on Adam, Lydia's like the first girl crush I've ever had & she's one of your ex's, brilliant" Aw Sarah #Corrie," followed by a broken heart emoji.
