Rihanna

"I won't say that we're just friends — me and Chris are really best, best friends," Rihanna corrected, smiling. "We both started our careers around the same time. He is one of the only people in the industry ... I trust and hang out with all the time. We are best friends, honestly, like brother and sister. If he was a boyfriend, I would say that."

Rihanna has banned umbrellas from her U.K. tour.

The 20-year-old star has insisted the item be confiscated from fans, in case they injure themselves trying to copy the dance routine to her hit song 'Umbrella.'

Producer Tricky Stewart tells how Rih Rih and Jay-Z transformed the track originally meant for Britney.
