Tina O’Brien says Helen Worth makes her feel "very loved and looked after" if she goes to her with a problem.
The ‘Coronation Street’ star – who plays Sarah Platt on the ITV soap – admits her on-screen mum Helen (Gail Platt) is also like a real-life mother figure to her when the cameras stop rolling, and she also loves watching her on-screen gran Sue Nicholls (Audrey Roberts) at work.
She said: "Helen is very caring and mothering, if I ever have a problem or I need advice I go to Helen, without a doubt. She really listens and always makes me feel very loved and looked after.
"Sue is wonderful; I love listening to Sue, I love watching Sue, I love Sue as Sue, I love Sue as Audrey. It is like a fake, weird family.
"To me, Sue and Helen are Coronation Street and to be around that, I go wow. The way they are as mother and daughter and how they wind each other up is so natural.
"That’s family to me and that is very clever."
Tina is also close to on-screen brother Jack P. Shepherd (David Platt), admitting he is "real wind-up merchant", and her on-screen daughter Lucy Fallon (Bethany Platt) even calls her mum when out of character.
She said: "Jack is a real wind-up merchant but I love him dearly so I guess that’s how I would feel about a little brother.
"Lucy actually calls me mum sometimes and Ben is like an older brother, wise and caring."
The 35-year-old actress enjoys working with her on-screen boyfriend Mikey North (Gary Windass), and admits she would find it "really difficult" if Sarah split from Gary because she loves starring alongside the 32-year-old actor.
She said: "It’s really difficult because I love working with Mikey! He is the greatest guy to work with professionally and we work so well, it’s like a dance.
"However if I was to advise Sarah I’d say that she should get away from Gary, he’s bad news.
"But I do think Sarah and Gary work so well and I really enjoy working with Mikey."
