The host of the US version of Pop Idol says he's fed up with Simon Cowell criticising his clothes.
Ryan Seacrest says he's been accused of looking like a cast member from Star Trek and Saturday Night Fever.
He says Cowell should look at his own wardrobe before he starts commenting on others.
"He has asked me if I've been hanging out with the cast of Star Trek," Seacrest tells TV Guide.
"Then he commented on my 'Saturday Night Fever wardrobe' and said 'Can't you make up your mind which generation you want to live in?'"
"Simon wears the same damn thing every episode.
"It's always a black shirt and black pants. Every seventh episode, he rotates with a white T-shirt."
