Corrie casts Leanne's (other) half-sister

Catherine Tyldesley has been cast as the daughter of the new Rovers landlady, Stella, played by Michelle Collins.  The official ITV Coronation Street website reports that Catherine, 24, will play Eva Price and her first Corrie scenes will be screened next month.

And so if this rumour is true, and Stella turns out to be Leanne's real mum, this means Leanne and Eva will be half-sisters, making Eva Leanne's second half-sister along with Toyah.
