Before James Arthur was crowned the winner of this year's X Factor, One Direction and Rihanna also performed live in Manchester.
Simon Cowell Wants Chris Brown And Rihanna For The X Factor?
The 'Turn Up The Music' singer and the 'You Da One' star are the most wanted stars on the music mogul's wish list.
Simon Cowell apparently wants to offer R&B singer Chris Brown a position on The X Factor USA following the announcement that LA Reid will be stepping down from his position on the next series of the show.
The 'Don't Wake Me Up' singer's former girlfriend Rihanna is also being lined-up for either the US or UK version of the reality show, according to The Sun.
"Simon is a huge admirer of Rihanna and knows she's star quality," a source told the publication. "As well as bringing an aura to the panel thanks to her current standing in music, she is also feisty and will make great TV.
"Simon loves these sort of characters."
Speaking about the possible addition of Chris on the show, the insider added: "The US X Factor has improved on the first season's ratings but it's got some way to go to reach Simon's expectations. Adding Chris to the panel will certainly create a talking point."
Britney Spears made her debut on the latest series of The US X Factor alongside Disney star Demi Lovato.
Meanwhile, Chris and Rihanna are rumoured to have rekindled their relationship in recent weeks after posing for pictures together and being spotted at a variety of nights out at the same venue.
