We have to admit, we didn't know she had these pipes either!

Nicole Scherzinger might be known as the sexy frontwoman for pop group The Pussycat Dolls, but she taught Simon Cowell a thing or two about her real X Factor on The X Factor Wednesday night!

After a 20-year-old woman gave an oversexed audition, Cowell said he felt like Scherzinger would have done the same when she was younger.

The songstress then put him in his place with a rousing rendition of Whitney Houston's diva-tastic "I Will Always Love You"! Watch above!
