After co-star Anton Yelchin's tragic death last week, the ballad—the lyrics include "You just don't let up, don't let up/You're taken over the beat of my body/But you lift me up, lift me up/If you take my pulse right now/It would feel just like a sledgehammer"—seemed to resonate deeply with the actors.
"After such an unimaginably sad week for our Star Trek family—[Rihanna] brings some light into the darkness," Quinto wrote in a caption.
Saldana mirrored his sentiments in her own post.
"A beautiful song during one of the most difficult times for our Star Trek family. We know Anton would be proud," she wrote.
