Rihanna fans who won the chance to travel with the star on her ‘777’ tour have criticised the trip.According to various reports, the ‘Bajan’ star has been repeatedly late to shows and flights while travelling the globe, and delaying journey times for the fans and journalists she invited along.Journalists hit out at Rihanna during a flight from Berlin to London on Monday (November 19), with one Australian writer streaking down the plane in protest.Guests on the trip have complained that they have rarely seen Rihanna, while The Sun reports the star has been hidden away in her panic room."They told us it was going to be exclusive with not that many people,” one fan said. "We were gonna go to sound checks and be front row.”Another added: "We’ve spent days waiting for her on the Tarmac to get on planes or waiting in coaches for hours on end."There’s more waiting when we arrive in each city too, lugging cases off buses to hotels then straight out again.” The Sun
