Coronation Street star, Sam Aston who plays Chesney in the award-winning ITV soap has admitted he fears he has that some of the scenes he has ahead will be tough to film– as his character Chesney Brown watches his girlfriend become a surrogate mum.

Fans of the show will know how Chesney’s girlfriend, Katy (Georgia May Foote) has offered to be a surrogate mother for her disabled sister, Izzy (Cherylee Houston) and her partner, Gary (Mikey North) after they discovered that would not be able to adopt due to Gary’s criminal record.

However, Sam fears there will be lots of tears shed if Chesney and Katy bond with the baby – despite them trying  try to stay hands-off during the pregnancy.

Sam said: “Chesney will look after Katy because he loves her but, as far as the pregnancy goes, he understands that Izzy and Gary will be much more involved than they were first time round.

“At the end of the day, Chesney respects the person Katy is and the decisions that she makes.

“He may struggle with the birth as it would bring back memories of baby Joseph.

“This may lead to problems with giving the baby to Izzy and Gary, as Katy and Chesney may grow attached.”

 Coronation Street can be seen Monday, Thursday and Friday evenings on ITV1/ITV1 HD.
