Keen eyed Emmerdale fans are hopeful that they have found out Reuben's dad after thinking that a soap star in the thick of the storyline has let slip a massive clue.
Fans are sure ever since Chloe Harris (played by Jessie Elland) gave birth to baby Reuben, that Mackenzie Boyd (Lawrence Robb) isn't the actual father, The Mirror reports.
The pair engaged in a one night stand before Mackenzie split with Charity Dingle so they could give their relationship a go to be a family.

Emmerdale viewers think that Nate Robinson (Jurell Carter) may be Reuben's father following the pair's previous romantic escapades.
The actor who plays Nate also recently revealed his romance with Chloe.
Nate has recently married Tracy Metcalfe (Amy Walsh) in scenes of the episode that aired last week.
The Express said that, Jurell shared: "I think obviously he’s had a fling with Chloe. That was just a sexual thing rather than any kind of romance or anything like that.
"He met Naomi, which they got on but again, work commitments and just not being on the same page got in the way.
"So I think he's finally got his match with Tracy and I feel like it's nice to see on screen as well."
Fans took to social media to mention their possible theory, with one writing: "If the baby somehow ended up being Nate's, Ruben would go from being Moira's nephew to Cain's grandson #Emmerdale."
Another said: "#Emmerdale After all this, Nate will be the baby’s father!"
"#emmerdale is Mack really the father? Didn't she sleep with Nate too? Al?," a third added.
But it looks as though if the predictions are true, it won't affect Nate's new marriage anytime soon.
Amy Walsh, who plays Tracy talked about their wedding but said it works out in the end. She said: "The wedding was sabotaged but that doesn't stop them and there's a little celebration but that might not go to plan either,.
"There are a lot of forks in the road and there may be a Dingle initiation as well. It is like domestic bliss with all the bumps that come with that. So we've got some issues coming up.
"But what's really nice to see I think in the next few coming episodes after the wedding is them, you know, hitting those bumps and then sailing over them."
