A restaurant trade group says it is insulted by a Super Bowl ad that stars Kevin Federline as a fast-food worker.

Nationwide Mutual Insurance Co.'s spot shows K-Fed, Britney Spears' ex, performing in a flashy music video. It turns out he's daydreaming while cooking fries at a fast-food joint.

The ad amounts to a "strong and direct insult to the 12.8 million Americans who work in the restaurant industry," National Restaurant Association President and Chief Executive Steven Anderson wrote in a letter to Nationwide. The ad "would give the impression that working in a restaurant is demeaning and unpleasant."
