Rihanna, full name Robyn Rihanna Fenty (born 20 February 1988; age 32), is a Barbadian singer, songwriter and actress. She recorded the Star Trek Beyond promotional single "Sledgehammer", which was written by Sia Furler. Rihanna also costarred with Sia in the 2015 remake of "Annie".
Rihanna inherited her love of Star Trek from her father during childhood, and said "Sledgehammer" is more important than recording a song for just any film, "because Star Trek is such a big deal across the globe."  Her song "Shut Up & Drive' was included in the soundtrack to 2008's Wild Child costarring Vanessa Branch, also that year, her hit "Take A Bow" was featured in the sex comedy The House Bunny starring Christopher McDonald. In 2009, Rihanna contributed "Live Your Life" to the megahit The Hangover costarring Rachael Harris.
In addition to her career as a singer, Rihanna has also built an acting career with roles in the science fiction film Battleship (2012, with Joe Chrest).
