Ellen DeGeneres is sticking to her guns, and that means NOT falling in line with the growing number of celebs who think it's time to at least give the Prez-elect a chance.

We got Ellen and wife Portia de Rossi out at Madeo ... after Ellen's record-setting win at the People's Choice Awards. She was in a celebratory mood -- right up until we asked if she was planning to watch the inauguration.

Sorry, Brian Littrell ... Ellen's not down with your program.
