The 'Diamonds' singer was spotted sporting a candy floss pink silky nightdress complete with sexy lace trims as she pounded the pavements in the Big Apple.
Who else would wear their nightie to run errands?!
Thankfully the starlet did cover up a little bit with the help of a blue denim jacket, rolling up the sleeves for an effortless vibe.
She also mismatched her outfit with a pair of black Converse, which looked brand spanking new judging by the bright white laces and soles!
And in true RiRi style she added some drama with heaps of bling, layering up a few gold necklaces while rocking a monochrome statement ring.
Her voluminous curly tresses were piled up high on the top of her head and she flaunted her usual beauty look of glowing skin, fluttery lashes and peachy plumped-up lips.
We just hope this whole PJs as outerwear thing doesn't catch on... we definitely don't look as good as Rihanna in ours!
