Nicole Scherzinger credits her motivation for a failed audition to be a Colgate dancing toothbrush. 

Speaking to The Sun newspaper, the 'Poison' singer explained that after being turned down by the global toothpaste brand to appear in a commercial she decided to prove the world wrong, and that she was capable of more than that:

"For TV stuff I auditioned for this Colgate commercial once. I was really desperate for the job."

"They didn't cast me as the dancing toothbrush and I would have been spectacular."

"The thing is, I could have used that money at that time."

She also explained that getting to where she is has been a struggle, but very much worthwhile:

"I was struggling and I tried so hard for the job. They were teaching us this choreography for the dancing toothbrush and just turned to me and said, 'No'. It was crushing."

"But I just felt at that moment I was going to prove them wrong. One day they would see I was SO that dancing toothbrush - and so much more."

"I could have been the best dancing toothbrush ever."
