Rihanna has been appointed to sing on Royal Caribbean's Oasis of the Seas on November 19. The Barbadian songstress' performance will be a part of the special three-night preview voyage scheduled for the 5,400-passenger vessel before the world's largest cruise ship is officially debuted in early December this year.

Beside celebrating the ship's debut, this gig will also become one of Rihanna's efforts to promote her new album "Rated R". She is scheduled to take the stage at Oasis of the Seas' outdoor AquaTheater, which is an unusual amphitheater-style space that serves as a pool by day and ocean-front theater by night.

Rihanna's other planned concert will take place on the album's release day on November 23. On the particular day, she will visit ABC for "Good Morning America" performance. Moreover, she is rumored to perform at 2009 American Music Awards.
