Simon Cowell is expected to announce the US 'X Factor' judges in a few weeks when he makes a ''surprise'' announcement about the show.
The music mogul - who will launch his hit pop star search TV show In America next year - plans to make a "surprise" announcement about the new series in December.
Being interview by his ex-girlfriend Terri Seymour for 'Extra', he said: "I'm going to make an announcement within three or four weeks, which is going to tell everyone everything. There will be some surprises."
Simon is still staying tight-lipped on who will be joining him on the judging panel, but did say: "OK, one of the judges has quite long hair."
The 50-year-old star is reportedly considering a number of big name American stars, including Katy Perry and Nicole Scherzinger, for a role as well as Girls Aloud singer Cheryl Cole - who is a judge on the British version along with Louis Walsh and Dannii Minogue.
However, Cheryl could lose out on a place on the US 'X Factor' thanks to British host Dermot O' Leary.
The presenter is said to have impressed American bosses - who are worried about the programme having too many UK stars - so much that they are willing to ditch her in order to have Dermot on board.
A source told heat magazine: "They were really impressed after watching him. He was in talks for hours but they didn't talk to Cheryl. Apparently, the job is his."
He said: "It's childish, it's disrespectful, bearing in mind what we achieved together. I wouldn't have liked it if anyone else said the same thing."
