Neighbours actress Kym Valentine has started dating former co-star Jonathon Dutton, according to a report.

The 32-year-old, best known for her role as Libby Kennedy on the soap, went public with the new romance at a David Gray concert in South Melbourne this week, the Herald Sun claims.

Dutton, 28, played Tad Reeves on Neighbours between 1998 and 2002. He has since appeared in a number of other Australian dramas, including The Secret Life Of Us, All Saints and Blue Heelers.

Speaking of her new relationship, Valentine is quoted as saying: "It is all early days."

The soap star parted from husband Fabio Tolli in 2007. She went on to have a short romance with actor Vince Colosimo last year.
