Rihanna looks DOG TIRED as she made her way to ‘SNL’ rehearsals. Someone’s been burning the candle at both ends! Yet I have to say, she’s one of those celebs who looks just as good make-up free as with her make-up.

I wonder if Rihanna will perform the song from her latest video, ‘Where Have You Been’? Perhaps performing perked her up a bit. Or maybe someone was nice enough to do a coffee run for her .
