Either we're having a serious case of déjà vu or Rihanna has stepped out in a sheet-and-sneaks combo before. At first we thought, how could that be? Then we remembered that this is the "Can't Remember To Forget You" singer we're talking about. Obviously she's worn this "style" before.
Apparently she can't remember to write down her plans for the night either and has to keep bolting out of the bedroom wearing her linens and grabbing the first pair of shoes on her floor.
