The 19-year-old sibling of the actress – who plays brassy barmaid Becky – may soon be following in her older sister’s footsteps after impressing the show’s bosses at an audition.
A source told The Sun: “Grace came to audition for a small role and blew bosses away. She’s as quirky as Katherine and she’s a cracking little actress. However, they couldn’t give her the part because she just looks too much like Katherine. It’s uncanny.
“It’s been agreed that if she joins the cast, she’s going to have to play one of Becky’s relatives, maybe even her sister.”
The source continued: “Sisters playing sisters would be a Corrie first.”
Katherine has just signed up for another two years on Coronation Street.
