Federline was slammed by members of the National Restaurant Association last week, who claimed the ad was insulting to fast-food workers.
The 28-year-old insists he never meant to disparage anyone, explaining, "The commercial is completely intended for me, making fun of myself and my own situation.
"It has nothing to do with anybody in the fast-food industry at all. So, you know, if we've offended anybody, I'm really sorry about that."
Federline appears in a 30-second spot for Nationwide Mutual Insurance where he is daydreaming about being a rap star while cooking French fries at a fast-food restaurant.
He adds, "It's a Saturday Night Live skit on myself. Maybe it'll land me some good roles in Hollywood!"
