Simon Cowell's ex, Sinitta, has revealed that the music mogul regards Dannii Minogue as his biggest threat on this year's 'X Factor'.
The 'So Macho' singer recently helped Cowell pick his final three contestants for the over-25s category, while Minogue recruited her sister Kylie to assist her as she whittled down the girls.
Speaking to the Daily Star Sunday she said: "Dannii is going to be a huge threat. It was a huge shock when we found out she's managed to get Kylie onside. Simon and I were incredibly jealous, really impressed.
"But you have to hand it to Dannii. She has come out firing on all cylinders this year. Dannii's bringing everything she's got to the fight. She's definitely won round one by fighting dirty, but Simon is not just going to roll over and die."
The star added that she expects Cheryl Cole, who is working with the boys, and the groups' mentor Louis Walsh to find the competition difficult as the weeks progress.
She added: "Cheryl is definitely going to find it a lot harder this year. She wants the sweet taste of success but I don't think she's going to get it. Simon's not going to let her have her own way or have it easy this year.
"And Dannii has come back being so strong, not to mention the fact she looks amazing.
"Dannii's hair and fashion choices are just fantastic so Cheryl is not the golden girl anymore. The public were so in love with Cheryl last year but she's got a lot to live up to and I think she will find it hard.
"I also think Louis will struggle. He has one strong group but that's it."
