Prior to sharing the heartbreaking news, Helen posted a cryptic quote about motherhood.
The On The Farm star’s post read: “A mama is always full of emotions, full of love, full of anxiety and worries, full of exhaustion and lack of energy, full of mum guilt and doubt, full of pride in her kids, full of pure joy.
“She feels it all, that’s the beauty of her, she carries it all too, and yet she gets up every day and does it all over again.”
As well as their daughter, Helen and Richie are also parents to young sons Ernie, six, and Louis, four.
Richie, who plays rugby for Leeds Rhinos, has not yet broken his silence on the split.
Express.co.uk has contacted Richie Myler’s representatives for comment.
