Two of the biggest voices in pop, Rihanna and Bruno Mars, delivered dynamic performances on X Factor UK this weekend, much to the delight of screaming fans.

Rihanna took to the stage clad in a tight-fitting black outfit to deliver a theatric performance of her single “Diamonds,” which has hit #1 on the charts, with intense pyrotechnics and simulated rain combining to make a memorable performance. Bruno Mars took a more traditional approach to his set donning in a black suit, shades and top hat, backed by a similarly dressed band, to deliver a rousing rendition of “Locked Out of Heaven,” from his upcoming album Unorthodox Jukebox. Watch back both performances below.
