Brit Clashing With Dolls?

Sources are snitching that things might not be so rosy between Britney Spears and the Pussycat Dolls, who are the opening act on her tour.

A source says, "Britney seems to have a chip on her shoulder about how the fans have been reacting to Nicole and the rest of the Pussycat Dolls.

"The group is riding high at the moment and are brilliant live. Britney seems to be a little uncomfortable with that, and Nicole has not exactly put her at ease.

"She has been making a point of celebrating the success of their hit song Jai Ho! and saying how much pride she takes in singing live. It's got to the point where they don't see each other at all now."
