Nicole Scherzinger says she has not yet found the song she will sing when it comes time to perform on the X Factor US this fall.

What she does know, however, is that it has to be one of the strongest songs on her solo debut album.

In an interview with Billboard.com, she said, "If it were up to me I would be performing every week."

"I have to make sure to have the right song [for 'X Factor']. It has to be a song that people will love. I'm judging a show where the prize is $5 million. The bar is raised. I know what I'm looking for and I'm going to make something special. My idea for the presentation is to throw everything into it. It's full throttle."

Her U.S. solo debut, "Killer Love,"  is out in November, most likely in the middle of the month when Scherzinger will have judged two or three live X Factor shows. She has already recorded more than 40 songs to be considered for her solo album, but insists that it "will not be finished until the very last minute. I don't know if I will ever feel like I have finished the album."

The second single, "Don't Hold Your Breath," was Scherzinger's first record to debut at No. 1 spot on the UK National Chart.

The song hit No.1 on both the Combined Singles Chart and Digital Download Chart, while the video has been watched more than 18.8 million times on Vevo.
