Rihanna buys diamonds for VIP guests at next world tour?

London: R&B star Rihanna has reportedly bought diamond bracelets for VIPs at her next world tour to provide an unforgettable experience.

The 24-year-old singing sensation has also ordered a diamond-encrusted microphone and mic stand for the shows, reported Sun online.

"She`s been offering to pay for the diamonds out of her own pocket because management weren`t keen. She just wants everyone who goes to the gigs to be totally overwhelmed," a source said.

Rihanna, who was named number one pop artist of 1992-2012 by Billboard, is set to commence her fifth tour, the Diamonds World Tour, in March 2013.
