Simon Cowell has n’t spoken to his four X Factor acts since telling them they were in his final four last month.

Leona Lewis, 21, said: “The last time we saw Simon was in Miami. We haven’t seen him for three weeks.”

Ashley McKenzie, 20, added: “I’ve seen him in the paper. He’s a busy man.”

Cowell has stayed in the US working on American Idol since the final audition of his under-25s.

At the same time, fellow judges Louis Walsh and Sharon Osbourne have given their acts presents and posh dinners.

All contestants are living in a house in North London under strict rules.

Cowell’s group had to watch in envy as Sharon’s over-25 contestants were driven off to dine at her Buckinghamshire home.

Rocker Ben Mills, 26, said: “I think they were jealous. It came at a stage we all really wanted to get out.”

Louis Walsh has been working closely with his groups, discussing what songs his acts want to sing and helping to ease their nerves.

He even sent 37-year-old Liz Ewing, from band The Unconventionals, to Harrods with cash to buy her a present for her four-year-old daughter Jasmin.
