Rosie O'Donnell's days on "The View" already numbered?

We’re told she seems “very depressed” and has few personal interactions with anyone off camera.  

The ratings are down and execs are blaming Rosie.

The honchos have tried talking with Rosie but they say it’s like talking to a wall. They doubt she will even finish the season and another season we’re told is “out of the question.”

Rosie’s rep tells TMZ … “This is absolutely false! Whoopi Goldberg has been the moderator since Whoopi was hired and Rosie knew that before she took the job.”
