Ottawa Senators center Mike Fisher and former American Idol singer Carrie Underwood are dating and the love match has apparently been going strong for months. Ms. Underwood, 25, was at the Sens-Toronto Maple Leafs game Saturday night where the Jumbotron ?Hug Cam? at the Air Canada Centre spotted her in a private VIP box hugging two people sitting next to her. Mr. Fisher?s parents and his brother, Bud, also a hockey player, were in the box watching the team go down to the Leafs in a 3-1 battle. The romance apparently began after Mr. Fisher, 28, went backstage following Ms. Underwood?s March 21 concert at Scotiabank Place where she performed before 7,700 country fans. The couple hit it off, say observers, and then began dating some time after their initial meeting.
