However, some viewers may not know that award-winning actress Suranne made her name as one of Steve McDonald's wives in Coronation Street.

Initially, Suranne had auditioned for the part of Genna Gregory on the soap in 2000, however, Jennifer James won that role.

But just weeks after her audition, Suranne was contacted by the bosses of Corrie, who offered the role of Karen Phillips on the soap.

Making her debut in Weatherfield as a machinist, she attracted the attention of many men including Steve and Peter Barlow.

But she would begin a relationship with Steve in 2001 and the pair quickly married after Janice Battersby made a bet with Karen.

The pair soon split, but their romance was back on after Steve proposed, for the second time, on a canal boat.

They planned to get married in February 2004, but at Christmas in 2003, Tracy Barlow told Steve he was the father of her unborn child after a one-night stand.

But the wedding day still went ahead, but not without its hiccups.

Tracy attended the ceremony and told all the guests that Steve was the baby's father.

While Karen was upset, she agreed to remarry Steve, after he said he had no intention to be with Tracy.

However, Steve and Karen would split again later that year with Karen eventually leaving Weatherfield on Boxing Day, after nearly accidentally killing Steve and Tracy's child Amy.
