Its Jessica Sutta, she did a song with Paul van Dyke called "white lies" and it reached Number 1 on the BIllboard hot club dance chart.
She was the pin up doll of the group before, she used to have black hair,pale skin and really red lips but now shes the red hair.

I still think shes the most good looking PCD.
