The actress went for a bizarre mix of denim and leather as she headed to Haven Spa in Soho, New York, yesterday (18 September).
She added a rock chick slogan tee and aviator sunnies, keeping her glorious strawberry blonde locks loose.
And while her leather chaps-style trousers look strange to us, it turns out Rihanna actually wore a similar pair two years ago.
The Bajan starlet sported them on a shopping trip in West Hollywood back in 2011, although we haven't spotted her in them since.
Guess the trend didn't catch on, then!
