The 22-year-old actress, who played the 48-year-old’s onscreen daughter Rosie Webster for 11 years, has told the Sunday People that she thinks the allegations made against Michael are 'vile'.
She said: “I can’t believe what Michael is going through. I was so shocked to hear the allegations had come back.
“It’s absolutely vile what is being said about him. It sickens you to the stomach and it is so upsetting what that man has been through.
“I have a lot of respect for the man because I have grown up with him.
“He’s a lovely, lovely man. Everyone at Coronation Street is behind him. It’s a respect thing.”
Michael Le Vell is facing 19 allegations including rape, indecent assault and sexual activity with a child.
Helen had previously called for the anonymity of those charged with child sex offences until they have been proven guilty.
She said: “I don’t think things like that should be in the press until it’s proven. It’s the worst thing to be accused of. It’s terrible. I have spoken to him and he knows I am there for him.
“He’s always been a great friend. I just wish him all the best. There’s absolutely no way he did it. I don’t believe it for a second.”
Michael is due to appear at crown court in Manchester on Wednesday.
