Jennifer Love Hewitt and fiance ROSS MCCALL were left red-faced at a recent concert - after Celine Dion dedicated a love song to them. In her first concert since she wrapped her five-year A New Day residency in Las Vegas in December (07), the singer singled out the newly-engaged couple and thanked them for coming to the show last week (ends15Feb08) before launching into her hit ballad The Power Of Love. Love Hewitt, 28, met the Scotsman when he made a 2006 guest appearance on her TV show The Ghost Whisperer. The pair became engaged last November (2007) after the Band Of Brothers star proposed while on vacation in Hawaii.
