The Coronation Street actress, whose fellow soap star Wallace recently cancelled her wedding to Vince Morse after discovering raunchy messages sent from him to his ex-partner, said that she believes that Wallace will bounce back from the scandal.
Marsh said in her New magazine column: "I couldn't believe my eyes when I read about Jessie Wallace cancelling her wedding at the very last minute. I actually felt sick for her when I saw the private photo that her fiancé, Vince Morse, sent to his ex splashed across the papers. What was he thinking?
"Jessie's been so unlucky in love and finally seemed to have found happiness with Vince - then he goes and does that, the snake! That picture was for his eyes only and although some people might think she was foolish taking it, when you're in love, you don't think your partner's going to betray you like that. I would trust [partner] Jamie [Lomas] with anything, so she must have been absolutely horrified."

Marsh continued: "Moving on, I know Jessie will bounce back from this. She's made of strong stuff and, having met her a few times over the years, I've got a lot of time for her. Good on her for kicking him out, too. If he'd done that to me, he'd have lost two vital parts of his body by now!"
Recent reports have implied that Wallace is considering taking Morse back, but his ex-wife Virginia Lewis has urged the EastEnders actress to dump him, describing him as a "serial cheat who's incapable of being faithful".
