After filing for divorce from her estranged husband Mike Comrie six months ago, it looks like Hilary Duff is moving on. The 27-year-old actress has sparked rumours that she is dating personal trainer Jason Walsh, after they were spotted at a club together in West Hollywood.

Last Friday Hilary and Jason attended the opening of Jason's new gym in Los Angeles before heading out to the club.

The pair looked completely thrilled to be in each other's company, joking around on the red carpet and striking one amusing pose after another.
