Watch the pair's live performances of 'Diamonds' and 'Locked Out Of Heaven' from the results show on Sunday.
Rihanna and Bruno Mars performed on The X Factor UK last night (25th November).
The pair's highly anticipated performances came on the same night Rylan Clark became the latest contestant to be voted off the talent show.
Rihanna delighted the studio audience with her latest single 'Diamonds', which saw her engulfed in a rainstorm while she sang the Vodafone Big Top 40 number one.
Wearing a figure-hugging black lace dress, RiRi's performance coincided with the global success of her chart-topping seventh album 'Unapologetic'.
Rihanna battled through ill health for her performance, telling her fans on Twitter afterwards that she was "sick".
She wrote: "I hate being sick!! I don't wanna do sh*t or talk to anybody right now!!! Can't even swallow, and that's no bueno!!"
Meanwhile, Bruno Mars took to the stage before Rihanna and performed his new single 'Locked Out Of Heaven'.
The US singer was joined by a full backing band, who danced along while playing their instruments.
