Will.I.Am says the collaboration between Rihanna and Cheryl Cole will happen when they find the right song. "Rihanna and Cheryl will be great when it happens. I first told Rihanna about Cheryl in 2009 when I said she's like the princess of England," dailystar.co.uk quoted the 37-year-old as
Singer Rihanna during a Gucci UNICEF dinner at The Oak Room at the Plaza in New York.
"No disrespect to the real royals but Cheryl's the pop princess and I've been telling Rihanna, so hopefully it will happen soon," he added.
