RiRi shared news of the single through her Instagram account, sharing a teaser for "Sledgehammer," a song which will appear on the upcoming soundtrack to Star Trek Beyond. While there is some music featured in the clip, it seems most likely that its simply a piece of the film's score, in which case fans will just have to wait until tomorrow to see what Rihanna has in store for them. According ti Rih's tweet, it'll be arriving at 8AM EST, so set your alarms!
