Rihanna Backs "Amazing" Tamera For X Factor Win

Rihanna has reportedly backed X Factorhopeful Tamera Foster, tipping her to be a global superstar.

When asked about the 16-year old singing sensation - who has been likened to RiRi in the past - the Pour It Up singer is quoted by The Daily Star as saying: "I got sent a link of her after she sang one of my songs at Boot Camp and I have been watching her ever since.

"The shows need to produce a superstar every two or three seasons to give them credibility, and she is already there in week five or whatever it is.

"Simon [Cowell] is a smart guy, he will know she can sell records all around the world and will sign her to his label."

She continued: "Tamera looks great, she has an amazing voice, and she has just the right amount of attitude."

Rihanna is also said to have commented on Foster's rumoured romance with fellow XF contestant Sam Callahan and her previous drug use, insisting it will not damage her future career.

The Diamonds hitmaker apparently claimed: "I really don't think it matters at all whether Tamera has made one or two mistakes in her past.

"Show me somebody who hasn't and I will show you a liar. All that matters now is that she works hard and gets where her talent means she should be."
