Rihanna will try to roll a lucky number by bringing her 777 tour to the tube in May.

A one-hour special documenting RiRi's whirlwind world tour, which made seven stops in seven countries in seven days, will air on FOX on May 6th. Besides concert footage, the show also includes clips shot on a 777 jet used to transport Rihanna, her entourage and more than 250 journalists and fans.

FOX has been courting Rihanna to sign on to replace Britney Spears in The X Factor. She hasn't given a firm yes or no to that offer.
