Rihanna's 777 tour becoming chaotic Rihanna (AAP) A promotional tour for Rihanna's latest album Unapologetic is swiftly turning into a PR nightmare. The tour was due to send the Barbadian singer along with 250 journalists and fans to seven cities in seven nights -- but has become mired in delays and complaints from those on board about fatigue and a notable absence of the star. To call the tour ambitious was a compliment from the very beginning as it required an airtight schedule. The 777 Tour kicked off in Mexico City, Mexico on Wednesday and almost failed at the first hurdle -- though it was out of her hands. The flight faced a delay after her first show when a 6.2 magnitude earthquake hit Mexico City, prompting a backlog of flight problems. The plane full of photographers, journalists and fans had to wait for the all clear before they could take-off from Mexico and travel to the second stop in Toronto, Canada. There was no such drama after that concert - but there was still a delay as Rihanna chose to chill backstage with her Battleship co-star Brooklyn Decker, who took a break from filming in the city to pay a visit, before boarding her plane bound for a Friday night gig in Sweden. The singer was two-and-a-half hours late for her third performance, in Stockholm, leading to an apparent three-hour flight delay. Having performed five shows so far, most recently in Berlin, she has already been fined over US$317,000,
