Rihanna does not stop. After being 90 minutes late to her gig in Zurich and partying all night, RiRi was off to celebrate Paris Fashion Week at the Chanel fashion show...and she did it all without sleep!

The 'Diamonds' songstress tweeted:

We do not know how this girl does it. Plus, she looked amazing without any sleep! Either she has a killer makeup artist  or she can honestly function without rest. If it's the latter, more power her to her unless it's messing with her work, which, uh, clearly it is.

Rihanna wore quite the interesting get-up to the fashion show, where she snapped pics with fans, her good friends and Chanel head designer and creative director, Karl Lagerfeld.  We're not quite sure what to make of her outfit, which resembles a cross between a bathrobe and a sweater dress. She accessorized the look with a whole slew of pearls and baubles, a cream-colored Chanel purse and black-tipped taupe stilettos. Oh, also, she wore it with no bra (surprise surprise), that effectively showed off her underboob tattoo.

Always devoted to her Navy, Rihanna was nice enough to take a selfie with one of her fans who was sitting close to her inside the Chanel runway show.
