UPDATE: Rihanna seems to be doing OK today. She was just spotted at the Gucci and Roc Nation pre-Grammy party at Soho House. She was wearing white and her hair was red, curly and very big. Also at the bash were Jay-Z, Beyonc, Florence Welch, Seal, Will Smith and Ellen Pompeo, among others.
No official word yet if flu-stricken Rihanna is feeling well enough yet to still perform at tomorrow's Grammys.
Word has it she's been on strict doctors orders to do nothing for the last couple of days, but she apparently hit rehearsals yesterday for the big show...
"She's had the flu, but you know there's a line that says the show must go on,'" Neil Portnow, president of the National Academy of Recording Arts &Sciences, told me at last night's MusiCares gala. "My guess is if it's humanly possible for her to do that, she'll want to do that and she will do it. We have our fingers crossed that she's taking good cares of herself and she'll be ready."
"We always think about these things," Portnow said. "If we have to go there, we'll figure it out. We always have a plan B."
As I was the first to tell you, Rihanna was so sick earlier this week that she had to cancel her five-song performance at Thursday's Unforgettable Evening gala benefiting EIF's Women's Cancer Research Fund.
