Are The Pussycat Dolls Getting sick of Nicole?

The background dolls are growing tired of Nicole recieving all the attention and credit for the groups work. In a recent show in the US, background doll Melody Thorton did a shout out to her family and added "Thankyou for supporting me, even though I'm not featured" and also going to say "don't let anyone stomp on your dreams"
Reporters and audience members said that Nicole gave Melody a dirty look after her shout out and the overall performance was awkard and tense.

Check out what happened.
