Nicole Scherzinger has admitted she is "scared" of duetting with her acts on X Factor because they are so good.
The former Pussycat Doll will perform two duets on Saturday night with James Arthur and Jahmene Douglas to try to get them both through to the last night, the Mirror reported.
When asked if she felt pressure, she said: "We're going to put on the best performance that we can, we're going to be really honest like we always are."
"I'm not going to lie, it's scary singing with these boys and I've sang with a lot of people! Will I overpower them? I don't think that will be possible with these two. They are very powerful, both of them. They are the strongest singers in the competition. I'm nervous because it's intimidating.
"I'm there mentor and their teacher telling them what to do and now I'm singing with them and whenever they open their mouths it's like baby Jesus, a rock star baby Jesus, coming out their mouths, I'm like 'oh my god, I don't want even want to sing, I just want to listen to them'. They are both such unbelievable talents, even after this series I'll never get used to hearing them. It's brand new every time," she added.
She also insisted there would be no "sour grapes" if one of her acts won over the other on Sunday.
"The good thing is is that we are a little tight unit here, we're a family, the boys really support one another.
"If we are standing there at the end, just the three of us, that means it will feel like we've already won," she said.
This week has seen her travel around 1000 miles up and down the country supporting her two acts and then heading to Manchester for the final. (ANI)
