Singer Rihanna is focusing on her tour instead
But the singer, real name Robyn Fenty, turned down the offer because of her upcoming tour.
‘It’s something that I would have loved to do, but our schedule doesn’t allow it,’ Rihanna, 23, told Ryan Seacrest on his US radio show on Wednesday.
‘We’re gonna be on tour for the rest of the year and it’s a demanding schedule to be on that show.
‘You have to kind of be around for a long time, months at a time, which is impossible for me… I’ll be on tour for the rest of the year.’
Rihanna will make an appearance on American Idol tonight, though, to perform new single California King Bed.
