Eagle-eyed Emmerdale viewers think they have worked out the real identity of Reuben's dad after an actor let slip a huge clue.
Fans are convinced Mackenzie Boyd (Lawrence Robb) isn't the real father, after the pair had a one night stand. Since the night, Mackenzie split with Charity Dingle to try and make the family work - but all may not be as it seems.
Some Emmerdale fans have taken to Twitter with a theory that Nate Robinson (Jurell Carter) could be Reuben's dad following a previous fling. Nate recently tied the knot with Tracy Metcalfe (Amy Walsh) on the soap last week.
