Frankly, I had to GOOG her to find out who she is...then, I recalled I had seen her on the drivel X Factor, being caustic or effusive, about some singer, as those 'judges' seem to be these days.
I got her confused with the look alike judge they had on for 20 mins, with a Scot accent.
I do have all her CDs from her Pussycat Dolls days.

Nice 'cushions', though.
