Rihanna brought a dose of 'Diamonds' to the U.K. edition of 'X Factor' on Nov. 25. RiRi took the spotlight in the middle of an onstage rainstorm that looked like diamonds falling from the sky. She covered up, wearing a long, black, lacy gown that covered everything from her neck to her decolletage to her legs. No skin shown here!

It was an elegant and stripped down (and no, not that type of stripped, which we'd expect from RiRi at this point) performance of her latest hit, thanks to that rain shower. She was soaking wet and vulnerable while she sang.

One day she's going to perform this song wearing a diamond outfit. Mark our words.
