Coronation Street viewers were gobsmacked this week when the Virgin Media One soap revealed the age of character Jack Webster.
Jack, played by actor Kyran Bowes, has been having a tough time in Weatherfield recently with the schoolboy getting bullied.
Corrie fans have watched on as he's picked on by other children for having 'two dads' after Jack found out that he was the result of an affair that Kevin Webster had with Tyrone Dobbs' late partner Molly while he was married to Sally Metcalfe.

Molly gave birth to Jack and when she tragically died on the cobbles in 2010, while Tyrone believed Jack was his biological child.
But on her death bed and in her final moments, Molly came clean to Sally and revealed that Kevin was Jack's real father.
On the Virgin Media soap last month, Jack found out that he was the product of an affair after overhearing a conversation between Kevin and his sister Debbie.
This week, Jack admitted to his dad that Nathan had been taunting him having found out that Tyrone initially thought he was his dad, Mirror UK reports.
During Wednesday's episode, Kevin got into an argument with Jack and was upset to hear his son say that he wasn't looking forward to having Kevin's wife Abi back.
However, Coronation Street fans were distracted by the fact that it was Jack's last day at school, making him 11 years old.
Taking to Twitter, one person wrote: "Hang on Jack is supposed to be ELEVEN!?! #corrie #coronationstreet."
Another tweeted: "Jack needs walking to school? Last day at primary? That makes the character about 10-11 but he looks and sounds about 19!!! #coronationstreet #corrie."
A third person posted: "Love how in #Corrie they keep stressing how Jack is like 11 years old when the young actor playing him is clearly around 15 years old."
And a fourth viewer added: "Did I just hear right Jack Webster is only 11 @itvcorrie I’m sure he’s about 14 #corrie."
Someone else commented: "Why is Jack in Corrie who looks about 15 in a class full of 8-9 year olds. Ridiculous. I’m sorry but he needs to be recast, why is he in a school with kids half his age #corrie."
A different person joked: Is Jack meant to be the same age as the rest of those schoolkids?! He looks like he could be their teacher! #Corrie #CoronationStreet."
And another added: "JACK IS SUPPOSED TO BE IN PRIMARY SCHOOL ??????? #corrie."
Actor Kyran is 15-years-old in real life but the character of Jack was born in September 2010, which makes him 11-years-old.
The teenager stepped into the role of Jack Webster back in 2016 as he replaced twins Jaxon and Maddox Beswick.
Coronation Street airs on Mondays, Wednesdays and Fridays at 8pm on Virgin Media One.
