Who knew Rihanna loved space so much? The music video for “Sledgehammer,†her Sia-penned single from the Star Trek: Beyond soundtrack, has arrived online after premiering in IMAX Thursday morning, and before we talk about the video, can you even imagine the type of person who gets up bright and early to go to an IMAX theater and see a Rihanna video? What is the rest of their day like? Anyway, the video is typically trippy and features Rihanna dancing around in a mauve desert with freaky tattoos and no eyebrows. No Horny Drake this time, but we can’t always be that lucky.
