Kiefer Sutherland has responded to Freddie Prinze Junior, who called the 24 star the "most unprofessional dude in the world" on Monday.
In an interview, Freddie said that working with Kiefer on the FOX show was so tough that he almost quit show business.
But Kiefer has nothing but good things to say about his former co-star. Sutherland's rep said, "Kiefer worked with Freddie Prinze Junior more than five years ago, and this is the first he has heard of Freddie‘s grievances. Kiefer enjoyed working with Freddie and wishes him the best."
