In May 2011, Danson teased an "exciting" upcoming storyline involving Leanne. Danson revealed that she was surprised by the storyline, saying "I thought now that and Peter are married they'll probably have a baby and do the expected thing. But I think I'm alright to say that it's not that. I would love to tell you it is! Keep watching." It was later reported that new character, Stella Price (Michelle Collins), would be revealed to be Leanne's biological mother. The storyline was confirmed in June 2011. Collins told "Soaplife" magazine that Stella has moved to Weatherfield as she has decided that it is the time to finally make herself known to Leanne. Stella was in a relationship with Les Battersby (Bruce Jones) and gave birth to Leanne when she was seventeen. Les started drinking and left her alone with Leanne and she struggled to cope. Stella left with every intention of coming back for Leanne once she was settled. When she did, Les would not let her near Leanne and Collins said that Stella "didn't stand a chance".
