Rihanna could be set to become a judge on the US version of X Factor, it has been reported.

The singer, who is riding high in the UK charts, will join the US version of reality talent show the X Factor, Look magazine reports.

"To get her on the show would give it real star power. Nicole Scherzinger and Cheryl Cole are also being considered for places on the judging panel, because they’ve got a proven track record of being great judges, but that doesn’t rule Rihanna out," a source told Look.

They added: "She has a massive appeal and a real edge to her. Simon knows she wouldn’t be afraid to give her opinion."

Meanwhile, Rihanna has opened up about her relationship with her estranged father.
