Katherine Kelly told Whats on TV at last night's British Soap Awards, that her real-life sister, Grace, may be joining Coronation Street as Becky's on-screen sister. How weird but fun does that sound?Katherine said about Becky McDonald: "It's very exciting, she's going to get a sister, which is an exclusive. Very, very soon a half-sister is going to come into her life. They are interested in my sister (Grace). She is the prefect age and she's a cracking actress and she is my sister, so she looks just like me. But she's in LA at drama school, so... I don't know if it will work."
