The actress, who plays Maria Connor in the ITV1 soap, split from the property developer in January after five years of marriage.
She has cited his "unreasonable behaviour" as grounds for ending the marriage, the Sunday Mirror reports.
She has since begun dating her Coronation Street co-star Will Thorp (Chris Gray), while Matt has been spotted with model Hayley Goodhead.
Speaking in January of Samia's new relationship, Matt said: "They have to live with what they've done. She's my wife. I love her and we've got a child. I'm just trying to get on with my life."
The former couple have a 19-month-old daughter together named Freya.
