FOX released a preview trailer for their upcoming special, Rihanna 777 on Wednesday. In the preview clip, the Pour It Up singer admits that while it may have only been the second night for the seven-day tour, it was already hard.

"Second show in, it's already feeling a little brutal," the Barbadian singer says in the clip before she and her crew take the stage in Toronto.

Rihanna 777 is a documentary that offers a full behind-the-scenes look on her seven day promotional tour where she performed in seven countries in seven days on a 777 Boeing airplane.

Rihanna's 777 tour was part of her efforts to promote her seventh album Unapologetic. She began in Mexico City on November 14. She then made stops at Toronto, Stockholm, Paris, Berlin, London and it ended in New York City on November 20. The grueling schedule paid off: the next day her first single off Unapologetic, Diamonds, landed No. 1 on the Billboard Hot 100. When Unapologetic was released shortly after, it sold 238,000 copies and debuted at No. 1.

The documentary will showcase not only Rihanna's performances on stage but the offstage antics in behind-the scenes footage. Fox acquired the exclusive worldwide rights to air the footage of the globetrotting pop singer who traveled with over 250 people.

The film promises to provide "an inside look at the singer's ambitious and often turbulent tour, from the sound of popping champagne corks on the plane, to the backstage chaos, to the singer's special worldwide appearances," FOX wrote in a statement.

Rihanna is currently on a Diamonds World Tour, her fourth in North America. She will head to Europe and wrap it up in South Africa in October.

Rihanna 777 premieres Monday, May 6 at 8pm EST on FOX.
