The hot blondes are challenging the hot brunettes. Which team would win?

This is a mismatch. Yvonne & Kimberly will destroy Rihanna & Nicole Scherzinger without any problems. 

This fight is finished after a few seconds.

Another Yvonne and Kimberly vote!

[Vassago]

Yvonne & Kim win by a double KO over Rihanna & Nicole.

The Pussycat Dolls go first: Nicole VS Kimberly. Nicole is the head of the group, the  main singer. That's why I think Nicole have beaten Kim a couple of time. Nicole wins this without doubt after a hard fight



On the other hand, Yvonne VS Rihanna...
