Coronation Street star Simon Gregson has been a soap star for almost 25 years, but his son thinks he’s a cleaner!

The funny revelation comes out in ITV’s new series Big Star’s Little Star, which asks kids to dish the dirt on their famous folks in front of millions of viewers.

Host Stephen Mulhern told TV Times that when he filmed a pilot episode with Simon, he asked Simon’s son what his his dad did for a living.

“He’s played Steve McDonald for 24 years, so Simon thought he might say he was a taxi driver,” says Stephen. “He actually thought his dad was a cleaner, because he cleans his car every other day! You get loads of lovely moments like that.”

Big Star’s Little Star starts on ITV next Wednesday – read the full interview with Stephen in the new issue of TV Times out today.
