Whiston, UK - MOL - Coronation Street actress Kym Lomas has asked for her surname to be changed back to Marsh in the ITV1 soap's credits. The actress filed for divorce from husband of a year Jamie last month citing his unreasonable behavior, despite her alleged affair with co-star Oliver Mellor. A source told the newspaper on Saturday: 'Kym is adamant that she will divorce Jamie and demonstrated how serious she was by asking Corrie to change her credits.'

According to the newspaper the EastEnders actor, 33, has told friends he 'plans to file his own divorce claim' citing her adultery. He believes that he is the one being seen as the bad guy in the situation which has left him feeling angry as he was the one that was cheated on. The source added: 'Kym has had enough and she wants this over quickly. But Jamie is spoiling for a fight and is determined not to go out quietly.' The couple's relationship allegedly broke down after reports revealed that the mother-of-three had a five month affair with the actor, who played Dr Matt Carter.

It will be the second divorce for the star, who married actor Jack Ryder in 2002, and was given a quick divorce after she admitted to adultery with her now-husband. Jamie, of Hollyoaks fame, but who now plays Jake Stone in the BBC1 soap, is alledged to have not returned to their home since news of the affair broke.

The estranged actors have a two-year-old daughter, Polly, but Kym also has a son David, 18, and daughter Emily, 15, with builder Dave Cunliffe. Kym was last spotted out and about last weekend looking stunning at The Concorde Hanger, Manchester Airport, for The Gavin Blyth Macmillan Ball. Wearing a black backless dress complete with diamante straps, the actress looked happy to pose for photographers on the red carpet.
