Jennifer Nettles Puts ‘Heart’ Into Super Bowl Ad (VIDEO)

Jennifer Nettles is the latest country star taking part in this Sunday's (Feb. 5) Super Bowl telecast, as the Sugarland singer will be heard singing Hank Williams' 'Your Cheatin' Heart' in a 30-second commercial for Pepsi MAX. The spot also includes TV legend Regis Philbin, who is seen greeting a Coca-Cola sales rep at a grocery store, after the rep wins a major contest in which the prize is a lifetime supply of Pepsi products. Watch a sneak peek of the Pepsi MAX commercial below.

Jennifer isn't the only country star Pepsi is using on Super Bowl weekend. Carrie Underwood will join Steven Tyler for a special 'CMT Crossroads: Steven Tyler & Carrie Underwood From the Pepsi Super Bowl Fan Jam,' set to air one night before the big game.

Other country artists appearing as part of the Super Bowl XLVI festivities include Darius Rucker, Sara Evans and Dierks Bentley, who will all make separate appearances at events leading up to Sunday night's match-up between the New England Patriots and the New York Giants. Meanwhile, Blake Shelton and his wife, Miranda Lambert, will perform 'America the Beautiful' prior to kick-off, with Kelly Clarkson singing the national anthem.

Jennifer and her duo partner Kristian Bush have been taking some much-needed time off in 2012, after dealing with the tragic Indiana State Fair tragic stage collapse in August, which killed seven people. They do have a handful of dates already on the books for the upcoming year, including shows in Mississippi, Wisconsin and Canada. See their concert schedule here.
