US Naomi Campbell will make a guest appearance in the second season finale of ABC's hit comedy 'Ugly Betty'.According to Fox News, a representative for ABC has confirmed that Campbell will play herself in the show. Speaking to the American Associated Press, 'Ugly Betty' actress Becki Newton said: "She's going to be in our last episode, which is exciting".

She added: "I've personally requested that I don't stand next to her because Amanda [Newton's character] would not like to be seen with such a tall, pretty person."

Newton, who plays receptionist Amanda Sommers, was unsure whether she would share scenes with the 37-year-old supermodel.

Campbell was originally announced as a guest star last year but didn't appear in the first season or the beginning of the second season, which was cut short because of the writers' strike.

Previous 'Ugly Betty' guest stars have included Victoria Beckham and Gene Simmons, who played himself and was revealed to be Amanda's father.

Newton said the Kiss musician would reprise his role in an upcoming episode.

ABC has already confirmed that the series will return for a third season.
