Cath Tyldesley, who plays Eva in Coronation Street, has revealed the inspiration behind her character Eva's famous laugh.
"I went to drama school with an opera singer, and she had a laugh which was quite similar and Eva's is a version of that," says Catherine in this week's TV Times.
"People keep sending me tweets asking for it as a ring tine. As if you'd want that as your ring tone!"
Ooh, I don't know...
