Rihanna red hair coat trench coat grey bodyguard stripes

Rihanna and her red hair looked somewhat sullen leaving Giorgio Baldi in Santa Monica last night - maybe because she wasn't dining with new BFF Nicki Minaj?

The two singers are collaborating on a new single together entitled "Fly."

Rihanna recently Tweeted the pic on the right, with the following caption:

"Me and Nikki in our new crib, lol! Gettin busy on set of FLY!!! Its so hard to keep my hands off!"

Apparently Ri was poking fun at the rumors that the twosome got a house together. Of course, Ri did forget how to spell her new BFF's name, but so what?

Best friends forever!
