Don't Kiss Paula Goodbye ... Just Yet

The door isn't completely slammed on Paula Abdul ...

Multiple "American Idol" insiders are telling TMZ there is a chance Paula will come back to the show. Reality -- better than a good chance.

We're told the conflict is ultimately all about money ... and buzz leading up to season 9.

But for now, "A.I." is full speed ahead -- auditions for the show are set for tomorrow ... without Abdul.
