Nicole: I've Whipped My Boys Into Shape
The X Factor jokes about taking a firm line with James and Jahmene...
Speaking at the press launch for this weekend's grand final of the ITV talent show, the former Pussycat Dolls star claimed she'd been a hard taskmistress.
According to The Sun, she said: "The boys have worked so hard and secretly I have a whip, so I hit them."
But the 34-year-old - who sported an unusual red-and-black cape for the event - admitted that it was really HER who was nervous about performing in tomorrow night's show.
She said: "Having worked with the boys a little bit this week, it's quite intimidating.
"I thought they were fricking amazing, I mean I've been doing this for quite some time, but they were just brilliant, they make it look so easy.
"It's a real honour to be able to [sing with them]. I would always rather be on stage than behind the desk, so this is going to be fun for me."
The three finalists are each singing a duet with their mentor tomorrow night, which means Nic will be taking to the stage twice - while Gary Barlow will perform with his act Christopher Maloney.
We told you this morning how Simon Cowell has reportedly ignored Maloney in his post-show planning.
